Subject: Use Gnulib ‘free-posix’ module
X-Git-Tag: v1.35~14
X-Git-Url: http://git.ipfire.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=5d6736e394a630b3f5173f2d95c963f7a68fbea2;p=thirdparty%2Ftar.git

Use Gnulib ‘free-posix’ module

Paxutils uses it so we should too.
* gnulib.modules: Add ‘free-posix’.
* src/misc.c (remove_any_file): Assume ‘free’ keeps errno.
