Subject: Add strtoimax() compatibility function.
X-Git-Tag: v1.7.8.2~23^2~2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=e3eed7f8d238e895922851315447f5df9c475f11;p=git.git

Add strtoimax() compatibility function.

Since systems that omit strtoumax() will likely omit strtomax() too, and
likewise for strtoull() and strtoll(), we arrange for the make variables
NO_STRTOUMAX and NO_STRTOULL to cover both the signed and unsigned
functions, and define compatibility implementations for them.
