Subject: m4: fix errors in shipped stdio.in.h
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e63a58ebfb2ead25cbc4eff065f0036de8718439;p=openwrt%2Fstaging%2Fldir.git

m4: fix errors in shipped stdio.in.h

M4 fails to build against glibc 2.16.x, the shipped stdio.in.h attempts to
wrap gets() with a warning which fails since gets() got removed from the
default _GNU_SOURCE featureset.
