When I try to build git master branch using gcc 4.7.1 on Debian
unstable amd64, I get:
gcc ../sysdeps/ieee754/dbl-64/wordsize-64/s_isnan.c -c -std=gnu99

Before I filed a bug, I wanted to check if this was a known issue. I
couldn't find anything mentioning that error message in a quick search
on Bugzilla.
