# Define NO_EXPAT if you do not have expat installed. git-http-push is
# not built, and you cannot push using http:// and https:// transports.
#
+# Define NO_GETTEXT if you don't want to build with Git with gettext
+# support. Building it requires GNU libintl or another gettext
+# implementation, and additionally libintl-perl at runtime.
+#
+# Define NEEDS_LIBINTL if you haven't set NO_GETTEXT and your system
+# needs to be explicitly linked to -lintl. It's defined automatically
+# on platforms where we don't expect glibc (Linux, Hurd,
+# GNU/kFreeBSD), which includes libintl.
+#
+# Define HAVE_LIBCHARSET_H if you haven't set NO_GETTEXT and you can't
+# trust the langinfo.h's nl_langinfo(CODESET) function to return the
+# current character set. GNU and Solaris have a nl_langinfo(CODESET),
+# FreeBSD can use either, but MinGW and some others need to use
+# libcharset.h's locale_charset() instead.
+#
+# Define GNU_GETTEXT if you're using the GNU implementation of
+# libintl. We define this everywhere except on Solaris, which has its
+# own gettext implementation. If GNU_GETTEXT is set we'll use GNU
+# extensions like `msgfmt --check'.
+#
+# Define GETTEXT_POISON to turn all strings that use gettext into
+# gibberish. This option should only be used by the Git developers to
+# check that the Git gettext implementation itself is sane.
+#
# Define EXPATDIR=/foo/bar if your expat header and library files are in
# /foo/bar/include and /foo/bar/lib directories.
