   This is a patch for gdb.base testsuite:

Thanks much!  I've incorporated all of these, with the exception of the
"set/show print args" test in default.exp, since I haven't received the
code in GDB that implements this (hint hint :-) ).

Interestingly, the removal of the empty third arg in gdb_test adds
about another 70 passes to the testsuite's Solaris run...
