After applied 2 patches enclosed here, I can compile glibc in CVS. But
I got so many failures in "make check":

It looks like the math functions are wrong. Replacing the new assembler
with the old one fixes the problem.

The problem is caused by
http://sourceware.org/ml/binutils/2005-02/msg00122.html
Gas no longer handles
fclass.m p6, p7 = farg0, @inf|@pos
correctly. Jan, could you please fix it?
Thanks.
