set apm_damn_fool_bios on standby request if another request is
already in progress (as is done in the suspend case).  Suggested
by Soren S. Jorvang in PR 5246, but diff in that PR cleaned up so
it'd still work right when debugging printfs were enabled.
Pull in prototypes from <ddb/db_run.h> and <ddb/db_access.h>.
If `SOFTWARE_SSTEP' is defined then kgdb_stub.c needs the single-step
emulation in db_run.c:

	- re-arrange `db_*_single_step()' and `db_*_temp_breakpoint()' -
	  which are only used in the `SOFTWARE_SSTEP' case - so these
	  are available to the KGDB code.
	- make other code in db_run.c conditional on `DDB'.
Pull in db_run.c and db_access.c if KGDB is defined.
Make the single-step support routines available to KGDB-only kernels as well.
Reengineering of libf2c as a single library (which g77 expects).  Includes
a GNU-like "config.h" to make the librare correctly compatible with
NetBSD.
Prepare assembler source for -mrtd kernels.
Prepare assembler source files for -mrtd kernels.
New macro KENTRY to declare assembler functions used by the kernel to
make -mrtd kernels possible.
If a good matching shared library is found, don't look in the next
directories. This is compatible with the SunOS behaviour. Also,
it fixes a problem where it was not possible for some 3rd party
package to have a library with the same name as a library already
in the system, and a lower version number. The highest version
would always be picked. This particular problem shows up with Mozilla,
which has a libutil.so.1.0
For the record, (c = *string++) should _NOT_ be turned into
((c = *string++) != '0') when quashing warnings.
add "screenblank" support.

refuse an inverse query if the length is not INT32SZ.  from vix.
Remember any source routes that may have accompanied a SYN.
Change a few things to reference /usr/include/paths.h instead of local
references. Fixing the default PATH is a bit more effort.
change some /dev/tty to paths.h _PATH_TTY
/tmp to _PATH_TMP from paths.h
Add note that -nostdlib is passed to the linker.
Remove the EGCS_BOOTSTRAP and only use the "smart check"
