Problem building 2.9.5.1 on Solaris

[Peter A. Friend]

I have been trying to build the latest gcc on Solaris 2.5.1 as well as
2.7 (both Sparc) with the same results.

For starters, I get a bunch of "#error ISA not supported" messages. Looks
like __sparc is not being defined somewhere? :


fixproto: populating `include'
/var/tmp/newgcc/gcc/include/curses.h:5: warning: #include_next in primary source file
fix-header: In file included from /usr/include/sys/types.h:14,
                 from /usr/include/sys/termios.h:20,

                 from /usr/include/termio.h:13,
                 from /usr/include/curses.h:48,
                 from /var/tmp/newgcc/gcc/include/curses.h:5,
                 from /var/tmp/newgcc/gcc/include/curses.h:5:
/usr/include/sys/isa_defs.h:252: #error ISA not supported
fix-header: In file included from /usr/include/limits.h:14,
                 from /var/tmp/newgcc/gcc/include/limits.h:117,
                 from /var/tmp/newgcc/gcc/include/syslimits.h:7,
                 from /var/tmp/newgcc/gcc/include/limits.h:11:
/usr/include/sys/isa_defs.h:252: #error ISA not supported

Of course, these errors may mean nothing. What gets weird is that if I
use the --prefix=/opt/gnu option to configure, then try a make, I get a
core dump. I do NOT get a core dump when I run the default (install in
/usr/local) configure and run make. I know that I should just install
in /usr/local as a workaround but I am out of room on that partition.

I am using gcc 2.8.1. Make is GNU 3.77.

TIA,
