Only include limits.h when actually used
The __extension__ seems to trigger a bug in gcc when there are no identifier specified afterwards. Testcase: echo "#include <stdlib.h>" > try.c && cc -O0 -c try.c try.c:2:0: error: expected identifier or '(' at end of input With -O2 it does not happen. We work around this by only pulling in limits.h when we actually need the PATH_MAX. Signed-off-by: Natanael Copa <ncopa@alpinelinux.org>
