Problem with weak_alias and strong_alias in gcc-4.1.0 with MIPS...

[Steven J. Hill]

Greetings.
I have a working MIPS cross toolchain with:
   binutils-2.15
   gcc-3.4.2
   glibc-2.3.4
   linux-2.6.12
and then decided to work with gcc-4.1.0 out of the cvs head. I am now
getting build problems with glibc-2.3.4 with the first major snafu
being:
   ../sysdeps/ieee754/dbl-64/s_isinf.c:29: error: 'isinf' aliased to 
undefined symbol '__isinf'
   ../sysdeps/ieee754/dbl-64/s_isinf.c:31: error: '__isinfl' aliased to 
undefined symbol '__isinf'
   ../sysdeps/ieee754/dbl-64/s_isinf.c:32: error: 'isinfl' aliased to 
undefined symbol '__isinf'

I am attempting to try and figure out what changed so drastically to
cause this. I also looked in GCC and glibc Bugzilla databases, but did
not find anything addressing this problem. Has anyone seen this
behavior? Thanks.
