gcc 2.95.2 has problems on HPUX 11

[Greg Christopher]

I am finding what appears to be lots of problems on hpux 11 when using
(and trying
to create) gcc 2.95.2.  At first I was able to create a compiler, but it
had problems
in the c preprocessor. Once that was fixed, it seemed to create other
problems.

One of the problems I was seeing was that  SIZE_TYPE was
#undef'd in your hp-specific config headers, and then redefined
incorrectly
to unsigned int. If you check the types.h for hpux 11, you'll find it's
an unsigned long. This meant that variables and parameters of
size_t weren't matching their prototypes. The bad pa-hpux.h header
results in a bug in cccp.c on line 4179. changing your override in
gcc/config/pa/pa-hpux*.h
seemed to fix this; this should be fixed more cleanly, probably by not
overriding the SIZE_TYPE definition in types.h

Once I got by this problem, gcc seemed to start choking when it
compiled itself during the bootstrap process. I am seeing the following
problems when it makes libgcc2.a:

**********

Note: my initial configure was done from the /usr/gcc directory, and
looks like this:

/usr/gcchold/gcc-2.95.2/configure --prefix=/user/unibat/compilers/hpux11
--with-gnu-as

(It looks like you need to tell the c compiler to use gnu AS, or you
can't debug c programs)

This appears to be a bug in the way c-decl.c handles arrays; apparently
a tree_overflow is
occurring.

I decided to stop here, since it looks like you probably haven't done
gcc for HPUX 11 yet.

Let  me know if I can give you any more information.
