4660 * callback.c: If HAVE_CONFIG_H is defined, include config.h from
4661 autoconf. If HAVE_UNISTD_H is defined, include unistd.h to get
4662 appropriate definitions of read, write, etc. Add prototype for
4663 system.
4664
4665Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
4666
4667 * Makefile.in (libcommon.a): Delete.
4668 (callback.o,targ-map.o): Delete, moved to Make-common.in.
4669 (gentmap,targ-vals.h,targ-map.c): Likewise.
4670 (run-autoconf): Delete.
4671 * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
4672 (common makefile fragment): Moved back into ...
4673 * Make-common.in: Resurrect.
4674 * configure.in (AC_LINK_FILES): Delete, unnecessary now.

4683
4684 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
4685 comments and single quotes. Fixes a problem found on hpux.
4686
4687Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
4688
4689 * aclocal.m4: Remove Make-common.in from dependencies.
4690 * (distclean): Remove targ-vals.def.
4691
4692 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
4693 into here. Makes insertion into makefiles easier. Also, change
4694 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
4695 targ-map.o, and run are built. They are now built in the
4696 individual simulator directories, taking sources from ../common as
4697 necessary. This replaces the merging of libcommon.a into
4698 linsim.a, which was problematic for the WinGDB build process.
4699 * run.c: Include config.h from . instead of ../common.
4700 * Make-common.in: Remove. It's no longer necessary.

4720 * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
4721 specific.
