+/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
+ for FUNCTION which will then trigger a compiler warning containing
+ the text of "literal string" anywhere that function is called, if
+ supported by the compiler. If the compiler does not support this
+ feature, the macro expands to an unused extern declaration.
+
+ This macro is useful for marking a function as a potential
+ portability trap, with the intent that "literal string" include
+ instructions on the replacement function that should be used
+ instead. However, one of the reasons that a function is a
+ portability trap is if it has the wrong signature. Declaring
+ FUNCTION with a different signature in C is a compilation error, so
+ this macro must use the same type as any existing declaration so
+ that programs that avoid the problematic FUNCTION do not fail to
+ compile merely because they included a header that poisoned the
+ function. But this implies that _GL_WARN_ON_USE is only safe to
+ use if FUNCTION is known to already have a declaration. Use of
+ this macro implies that there must not be any other macro hiding
+ the declaration of FUNCTION; but undefining FUNCTION first is part
+ of the poisoning process anyway (although for symbols that are
+ provided only via a macro, the result is a compilation error rather
+ than a warning containing "literal string"). Also note that in
+ C++, it is only safe to use if FUNCTION has no overloads.
+
+ For an example, it is possible to poison 'getline' by:
+ - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
+ [getline]) in configure.ac, which potentially defines
+ HAVE_RAW_DECL_GETLINE
+ - adding this code to a header that wraps the system <stdio.h>:
+ #undef getline
+ #if HAVE_RAW_DECL_GETLINE
+ _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
+ "not universally present; use the gnulib module getline");
+ #endif
+
+ It is not possible to directly poison global variables. But it is
+ possible to write a wrapper accessor function, and poison that
+ (less common usage, like &environ, will cause a compilation error
+ rather than issue the nice warning, but the end result of informing
+ the developer about their portability problem is still achieved):
+ #if HAVE_RAW_DECL_ENVIRON
+ static inline char ***rpl_environ (void) { return &environ; }
+ _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");

- # Darwin 7.5 has nl_langinfo(CODESET), but sometimes its value is

- # - It returns the empty string when LANG is set to a locale of the
- # form ll_CC, although ll_CC/LC_CTYPE is a symlink to an UTF-8
- # LC_CTYPE file.
- # - The environment variables LANG, LC_CTYPE, LC_ALL are not set by
- # the system; nl_langinfo(CODESET) returns "US-ASCII" in this case.
- # - The documentation says:
- # "... all code that calls BSD system routines should ensure
- # that the const *char parameters of these routines are in UTF-8
- # encoding. All BSD system functions expect their string
- # parameters to be in UTF-8 encoding and nothing else."
- # It also says
- # "An additional caveat is that string parameters for files,
- # paths, and other file-system entities must be in canonical
- # UTF-8. In a canonical UTF-8 Unicode string, all decomposable
- # characters are decomposed ..."
- # but this is not true: You can pass non-decomposed UTF-8 strings
- # to file system functions, and it is the OS which will convert
- # them to decomposed UTF-8 before accessing the file system.
- # - The Apple Terminal application displays UTF-8 by default.
- # - However, other applications are free to use different encodings:
- # - xterm uses ISO-8859-1 by default.
- # - TextEdit uses MacRoman by default.
- # We prefer UTF-8 over decomposed UTF-8-MAC because one should
- # minimize the use of decomposed Unicode. Unfortunately, through the
- # Darwin file system, decomposed UTF-8 strings are leaked into user
- # space nevertheless.
- # Then there are also the locales with encodings other than US-ASCII
- # and UTF-8. These locales can be occasionally useful to users (e.g.
- # when grepping through ISO-8859-1 encoded text files), when all their
- # file names are in US-ASCII.

+ # LC_CTYPE file.
+ # - The environment variables LANG, LC_CTYPE, LC_ALL are not set by
+ # the system; nl_langinfo(CODESET) returns "US-ASCII" in this case.
+ # - The documentation says:
+ # "... all code that calls BSD system routines should ensure
+ # that the const *char parameters of these routines are in UTF-8
+ # encoding. All BSD system functions expect their string
+ # parameters to be in UTF-8 encoding and nothing else."
+ # It also says
+ # "An additional caveat is that string parameters for files,
+ # paths, and other file-system entities must be in canonical
+ # UTF-8. In a canonical UTF-8 Unicode string, all decomposable
+ # characters are decomposed ..."
+ # but this is not true: You can pass non-decomposed UTF-8 strings
+ # to file system functions, and it is the OS which will convert
+ # them to decomposed UTF-8 before accessing the file system.
+ # - The Apple Terminal application displays UTF-8 by default.
+ # - However, other applications are free to use different encodings:
+ # - xterm uses ISO-8859-1 by default.
+ # - TextEdit uses MacRoman by default.
+ # We prefer UTF-8 over decomposed UTF-8-MAC because one should
+ # minimize the use of decomposed Unicode. Unfortunately, through the
+ # Darwin file system, decomposed UTF-8 strings are leaked into user
+ # space nevertheless.
+ # Then there are also the locales with encodings other than US-ASCII
+ # and UTF-8. These locales can be occasionally useful to users (e.g.
+ # when grepping through ISO-8859-1 encoded text files), when all their

-/* Unlike standard Unix `getopt', functions like `getopt_long'

+/* This version of `getopt' appears to the caller like standard Unix `getopt'

+ to intersperse the options with the other arguments.
As `getopt_long' works, it permutes the elements of ARGV so that,
when it is done, all the options precede everything else. Thus
Using `getopt' or setting the environment variable POSIXLY_CORRECT
disables permutation.
- Then the application's behavior is completely standard.

+ support for this kind of constant expression. In the

+
+ We compute tmp =

+ That is, we perform the following operations:
+ 1. Subtract repeated_one.
+ 2. & ~longword1.
+ 3. & a mask consisting of 0x80 in every byte.
+ Consider what happens in each byte:
+ - If a byte of longword1 is zero, step 1 and 2 transform it into 0xff,
+ and step 3 transforms it into 0x80. A carry can also be propagated
+ to more significant bytes.
+ - If a byte of longword1 is nonzero, let its lowest 1 bit be at
+ position k (0 <= k <= 7); so the lowest k bits are 0. After step 1,
+ the byte ends in a single bit of value 0 and k bits of value 1.
+ After step 2, the result is just k bits of value 1: 2^k - 1. After
+ step 3, the result is 0. And no carry is produced.
+ So, if longword1 has only non-zero bytes, tmp is zero.
+ Whereas if longword1 has a zero byte, call j the position of the least
+ significant zero byte. Then the result has a zero at positions 0, ...,
+ j-1 and a 0x80 at position j. We cannot predict the result at the more
+ significant bytes (positions j+1..3), but it does not matter since we
+ already have a non-zero bit at position 8*j+7.
+
+ So, the test whether any byte in longword1 is zero is equivalent to

+/* Set up the following warnings, based on which modules are in use.
+ GNU Coding Standards discourage the use of fseek, since it imposes
+ an arbitrary limitation on some 32-bit hosts. Remember that the
+ fseek module depends on the fseeko module, so we only have three
+ cases to consider:
+
+ 1. The developer is not using either module. Issue a warning under
+ GNULIB_POSIXCHECK for both functions, to remind them that both
+ functions have bugs on some systems. _GL_NO_LARGE_FILES has no
+ impact on this warning.
+
+ 2. The developer is using both modules. They may be unaware of the
+ arbitrary limitations of fseek, so issue a warning under
+ GNULIB_POSIXCHECK. On the other hand, they may be using both
+ modules intentionally, so the developer can define
+ _GL_NO_LARGE_FILES in the compilation units where the use of fseek
+ is safe, to silence the warning.
+
+ 3. The developer is using the fseeko module, but not fseek. Gnulib
+ guarantees that fseek will still work around platform bugs in that
+ case, but we presume that the developer is aware of the pitfalls of
+ fseek and was trying to avoid it, so issue a warning even when
+ GNULIB_POSIXCHECK is undefined. Again, _GL_NO_LARGE_FILES can be
+ defined to silence the warning in particular compilation units.
+ In C++ compilations with GNULIB_NAMESPACE, in order to avoid that
+ fseek gets defined as a macro, it is recommended that the developer
+ uses the fseek module, even if he is not calling the fseek function.
+
+ Most gnulib clients that perform stream operations should fall into
+ category 3. */

+ A critical factorization has the property that the local period
+ equals the global period. All strings have at least one critical
+ factorization with the left half smaller than the global period.
+
+ Given an ordered alphabet, a critical factorization can be computed
