When I try building glibc from git master branch on an up-to-date Debian sid
amd64 system, with gcc-4.7 version 4.7.1-1, I get this error:

Attaching s_isnan.i from running this command with -save-temps.
BTW, if I make -k, then aside from the inevitable errors from libc.a and
libc.so not being built, the only errors I get are in s_isnan.c, s_finite.c,
s_isnanf.c, and s_finitef.c. And then later, in the others stage,
fraiseexcpt.c.
