X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e184ac3a105a4a45b920bf2cdaa701a683c781a2;p=thirdparty%2Fglibc.git

glob: Silence warning about void pointer arithmetic

Sync with gnulib 0e14f025d2.

Checked on x86_64-linux-gnu.

	* lib/glob.c (glob): Use a 'char *', not a 'void *', in pointer
	arithmetic.
