alpha support

[Bowie Owens]

Hi,

I am trying to get GNU as going on the OSF1 V4.0 1229 alpha we have
at work. Binutils-2.11.2 does not compile as is, there is a problem
with LITUSE_BASE not being defined gas/config/tc-alpha.c. I must admit
I don't really know what is going on, but if the defines are moved
above the #ifdef RELOC_OP_P then everything compiles ok. Below are the
results of diff -C 5. I would appreciate it if someone with a bit more
understanding could take a look and check if that is a reasonable way
to fix the problem.

Having made that change, the next thing I want to do is build gcc (2.95.3)
to use the GNU as and ld (--with-gnu-as and --with-gnu-ld). However,
I have run into a problem here as well. When the first build of xgcc
tries to compile libio/floatconv.c the assembler fails on a floating
point constant: ``floatconv.s:2184: Error: cannot create floating-point
number''. I have attached floatconv.s.gz.
