[PATCH] Misc Alpha stuff for glibc

[Jakub Jelinek]

Hi!

When trying to compile current glibc on Alpha, I came accross these:

With this patch in, the compilation still chokes during compilation of conj.c on:
In file included from ../include/bits/cmathcalls.h:1,
                 from ../math/complex.h:80,
                 from ../include/complex.h:1,
                 from conj.c:21:
../math/bits/cmathcalls.h: In function `cimagf':
../math/bits/cmathcalls.h:139: Unable to access imaginary part of complex value in a hard register on this target
(gcc 2.95.3).
gcc does not like the cimagf complex float inline (but if I ifdef that
inline out for alpha, it chokes later on on conjf.c).
What's the proper solution for this, Richard?
