struct target_waitstatus. Change status argument to target_wait to
be struct target_waitstatus * instead of int *.
* target.h, infrun.c, all targets: Change type of signal arguments
to resume(), proceed(), and target_resume() from int to enum
target_signal.
* All targets (*_wait, *_resume): Change accordingly.
* infcmd.c (program_info, signal_command), throughout infrun.c,
* fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
* convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
signal code stuff right with the new signals would be non-trivial).
* inferior.h (stop_signal): Make it enum target_signal not int.
* target.c, target.h (target_signal_to_string, target_signal_to_name,
target_signal_from_name): New functions.
* inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
store_waitstatus): New functions.
* procfs.c (procfs_notice_signals): Use them.
* i960-tdep.c (i960_fault_to_signal): New function, to replace
print_fault.
* config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
Change all references to stdout/stderr to gdb_stdout/gdb_stderr.
Replace all calls to stdio output functions with calls to
corresponding _unfiltered functions (`fprintf_unfiltered')
Replaced calls to fopen for output to gdb_fopen.
Added sufficient goo to utils.c and defs.h to make the above work.
The net effect is that stdio output functions are only directly used
in utils.c. Elsewhere, the _unfiltered and _filtered functions and
GDB_FILE type are used.
In the near future, GDB_FILE will stop being equivalant to FILE.
The semantics of some commands has changed in a very subtle way:
called in the right context, they may cause new occurences of
prompt_for_continue() behavior. The testsuite doesn't notice anything
like this, though.
Please respect this change by not reintroducing stdio output
dependencies in the main body of gdb code. All output from commands
should go to a GDB_FILE.
Target-specific code can still use stdio directly to communicate with
targets.

find_sym_fns() for remapped symbol files, in case of any changes
since the last mapping.
libiberty/strsignal.c. Widespread changes to use libiberty/strerror.c
functions for errno manipulations and libiberty/strsignal.c for signo
(signals) manipulations.
character type is unsigned. Add some cases to the tables in procfs.c
for constants defined in newer SVR4 systems and reorder the tests for
ioctl support of resetting the inherit-on-fork flag to favor the latest
method using PIOCRESET.
* All GDB files that #include defs.h: Removed stdio.h.
(defs.h): #include stdio.h.
This has been tested by building GDBs for all targets hosted on Sun4.
None of the build problems were related to stdio.h inclusion. (n.b.
many configurations don't build for other reasons.)
command that prints /proc specific information, changes to solib.c to
allow more flexible handling of finding the dynamic linker structures,
changes to utils.c and defs.h to add a new null_cleanup() function to
serve as an anchor point for cleanup chains with no obvious "first
cleanup".
core file (core.c), permanently remove the register_addr() stub (elfread.c),
move a misplaced #endif (procfs.c), and add fetch_core_registers func for
core file support (procfs.c).
