I don't observe this problem when I build with GCC 4.9.1.  src/Makefile 
says "CC = gcc -std=gnu99", so it works.  Perhaps you overrode CC?  Or 
maybe you have an old version of autoconf?

While we're on the topic, --enable-gcc-warnings generates false alarms 
when combined with arbitrary other options like 
--enable-check-lisp-object-type, CFLAGS='-g3 -O0', etc.  I do not take 
the trouble to pacify GCC for all combinations of build options, just 
for the default ones.
