	* kern/exception.c (exception_no_server): Comment out the suspend
	code; it's useful for special case debugging, but causes problems
	in general.
Wed Apr 16 12:52:25 1997  Thomas Bushnell, n/BSG  <thomas@gnu.ai.mit.edu>

	* Makefile.in (cross-lexxer.o lexxer.o): Add pump-priming
	dependency on cpu.h.  Reported by Marcus G. Daniels
	(marcus@cathcart.sysc.pdx.edu).

	* configure.in: Fail if configure target is not for GNU os.

	* Makefile.in (./cross-mig): New rule.
	(mkinstalldirs): Add $(libexecdir).
	* configure.in: Recognize i686.
	Reported by Marcus G. Daniels (marcus@cathcart.sysc.pdx.edu).
Wed Apr 16 12:52:25 1997  Thomas Bushnell, n/BSG  <thomas@gnu.ai.mit.edu>

	* i386/Drivers.in (com): Delete option.  It's required by
	kd_mouse.c.
	* i386/Makefrag (i386at-files): Add com.c.
	(driver-files): Delete variable.
	* i386/bogus/com.h: Revert change of March 10.
	* i386/device-drivers.h.in (CONFIG_MACH_COM): Delete option.
	Bug report from Marcus G. Daniels (marcus@cathcart.sysc.pdx.edu).
Wed Apr 16 16:55:36 1997  Marcus G. Daniels  <marcus@cathcart.sysc.pdx.edu>

	* configure.in: Replace AC_PROG_CC with AC_PROG_CC_LOCAL.
	If cross compiling do Lex/Yacc checks with BUILD_CC.
        Check CC and BUILD_CC for libraries having the needed support,
	and substitute discovery in installed_clib.

	* aclocal.m4: New file.  These replacement macros are to handle
	the case where there is a cross compiler but no supporting files.

	* Makefile.in (installed-clib): Don't hardwire a Hurd libcrt.a.
	(cross_linkable): Only define cross-migcom variable when it will
	be possible to build it.
	(all, install): Use $(cross-migcom).
	(install): Install cross-migcom only if was to be built.
	(mkinstalldirs): Add $(bindir), $(includedir)/mach/exec
	(cross-lexxer.o lexxer.o): lexxer.o needs cpu.h.
	(./cross-migcom): Prevent dependency generation for cross-* MiG files
	unless they can actually be built.
Wed Apr 23 13:21:23 1997  Thomas Bushnell, n/BSG  <thomas@gnu.ai.mit.edu>

	* configure.in (BUILD_CC): Use AC_CHECK_PROGS, not AC_CHECK_PROG,
	since we are checking multiple names.

	* configure.in (kdb): New --enable option.
	* Makefile.in (DEFINES): Add @DEFS@.

	* Makefile.in (clean, distclean, mostlyclean, maintainter-clean):
	New targets.
	(all-archs-configures): New variable.
	(MIG): Change to ./local-mig.
	(./local-mig): Change to build this instead of ./mig
	(check-clib-routines): Use nm -g in case there are local symbols.
	Suggested by Matthew Wilcox (willy@odie.barnet.ac.uk).

	* configure.in: Add AC_PREREQ for version 2.12.
	* i386/Drivers.in: Likewise.

	* configure.in: Add AC_PREREQ for version 2.12.
	* i386/Drivers.in: Likewise.
[MACH_KDB]: Add include of <kern/task.h>.
.
1997-04-30  Marcus G. Daniels  <marcus@cathcart.sysc.pdx.edu>

	* Makefile.in (clib-routines): Add htons not because it is necessary,
	but because libc5 systems will bring it in.
	(check-clib-routines): Tolerate extra weak symbols.
Wed Apr 23 13:21:23 1997  Thomas Bushnell, n/BSG  <thomas@gnu.ai.mit.edu>

	* configure.in (kdb): New --enable option.
	* Makefile.in (DEFINES): Add @DEFS@.
	* bogus/mach_kdb.h: Make this file zero length; we get MACH_KDB
	from configure now.
