[Bug libstdc++/21178] New: GCC4 series fails to compile glibc 2.3.x

["tobias at yoper dot com" <gcc-bugzilla at gcc dot gnu dot org>]

First entry so please stay calm and point me towards to your rules to apply to them.

I tried to use GCC4 to compile a whole LFS toolchain. I compiled several
GCC-4.X.X with GCC 3.4.3 and furthermore started to compile using GCC4. I used
pretty clean environments based on LFS.

No matter what I did here is the last command which seems to cause the failure:

gcc ../sysdeps/ieee754/dbl-64/s_isinf.c -c -std=gnu99 -O3 -Wall -Winline

The result is the following:

Using gcc -v -save-temps I got the following:

I hope I sent not to much or less information. This is completely reproducable.
Using gcc-3.4.3 in exactly the same environment does work properly. 

Contact me , when you need further information. I have the .i and the .s file
when somebody needs them.


Thanks Tobias
