I ran the testsuite on mips-irix, and got one real semi-regression:

    info proc^M
    Not supported on this target.^M
    (gdb) FAIL: gdb.base/info-proc.exp: info proc without a process

I think it's just a matter of the output having changed. I couldn't
verify it completely, because I had lost the gdb.log file from the
reference run (they are now split, and I only saved the top one).
If it wasn't intended, I'd still consider this an improvement since
the expected output was:

    No current process: <something like please select one>

I never feel completely confident about runs on mips-irix, because
GDB does not work at all with programs that use threading. AdaCore
has some local changes regarding this feature, but they are very
hacky and would probably not pass a normal review.

I cannot test using the standard testsuite on sparc-solaris. But
I can run our testsuite. So I applied your changes to our own tree,
and ran the testsuite. Found no regression. I think that's an extra
vote of confidence.
