so, and what version.
ANSI compiler warnings.

through the target vector.

operands to memory management instructions, from WRS.
Replace with simple default to C before processing any init
files. There MUST be a language set, even in the absence of
init files or executables, or expression parsing fails.
symfile.c. Fixup places where command files are processed to
be consistent in setting a default language if none has been
previously set.

(FP) value in the frame_info struct if it is zero (as from top of
execution stack).
(setup_arbitrary_frame): Implement FRAME_SPECIFICATION_DYADIC.
* mips-xdep.c (fetch_inferior_registers): ZERO_REGNUM always
comes back as zero. So does FP_REGNUM, as a trigger for
init_extra_frame_info.

the program counter set before INIT_EXTRA_FRAME_INFO is run.

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
here; it is dealt with at a gdb-target-independent level.
* rs6000-tdep.c (single_step): Don't call ptrace, we are a
high toned routine. Fix return type to void.
before printing anything, and again afterward. Fix comments.
(vfprintf_filtered): Eliminate static buffer; use auto buffer,
or alloca() if needed.

detect native versus cross-host.
termination condition.
(full_filename): Don't prepend dirname if filename begins with /.
(breakpoint_notify, kernel_dispatch): Deal with DynamicLoad
messages properly!!
(getpty (NCR)): Lotsa bug fixes...
(kernel_dispatch (case StopRType)): Use kill() instead of
killpg() so we can deal with losing systems...
(wait_for_events): Work around NCR select() lossage. It doesn't
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.
