symfile.c. Fixup places where command files are processed to
be consistent in setting a default language if none has been
previously set.

(FRAME_SPECIFICATION_DYADIC): Ask for two args in frame command.
Briefly explain MIPS stacks in GDB.
Rich and I believe the "real problem" was that both single_step
and target_resume were issuing PT_CONTINUE calls. This would
cause the second PT_CONTINUE to sometimes fail because the process
was already running.
* infptrace.c (child_resume): Remove AIX_BUGGY_PTRACE_CALL kludge.
* infptrace.c (child_resume): Don't deal with NO_SINGLE_STEP

messages properly!!
(getpty (NCR)): Lotsa bug fixes...
(kernel_dispatch (case StopRType)): Use kill() instead of
killpg() so we can deal with losing systems...

zero out readfds when select() returns zero.
(energize_initialize): Use I_SETSIG to get SIGIO interrupts. Use
getcwd() instead of getwd() (NCR getwd() seg faults).
(energize_wait): Use sigaction() for NCR. Their version of signal()
is unreliable by default.

* config/sun4.{mh,mt}: Remove (use identical sun4os4.*).
sub-variants of SunOS, e.g. sunos4* to match sunos4.1.1.

followed by pointer into string being demangled, followed by
pointer to the string where the result is being stored, followed
by other args. Also generally replace most variables of name

query string, to turn off wrapping and flush any buffered output.

seen by the user.

evaluate subscript for types without a target type, rather
than dumping core by using the NULL pointer.

* symtab.c (lookup_symbol, lookup_demangled_block_symbol,
lookup_demangled_partial_symbol,): Ask demangle_and_match to

against signed quantities. The right fix is probably to make
it all unsigned, but this is a small, safe fix for this release.
