4256 autoconf. If HAVE_UNISTD_H is defined, include unistd.h to get
4257 appropriate definitions of read, write, etc. Add prototype for
4258 system.

4260Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
4261
4262 * Makefile.in (libcommon.a): Delete.
4263 (callback.o,targ-map.o): Delete, moved to Make-common.in.
4264 (gentmap,targ-vals.h,targ-map.c): Likewise.
4265 (run-autoconf): Delete.
4266 * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
4267 (common makefile fragment): Moved back into ...
4268 * Make-common.in: Resurrect.
4269 * configure.in (AC_LINK_FILES): Delete, unnecessary now.

4278
4279 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
4280 comments and single quotes. Fixes a problem found on hpux.
4281
4282Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
4283
4284 * aclocal.m4: Remove Make-common.in from dependencies.
4285 * (distclean): Remove targ-vals.def.
4286
4287 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
4288 into here. Makes insertion into makefiles easier. Also, change
4289 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
4290 targ-map.o, and run are built. They are now built in the
4291 individual simulator directories, taking sources from ../common as
4292 necessary. This replaces the merging of libcommon.a into
4293 linsim.a, which was problematic for the WinGDB build process.
4294 * run.c: Include config.h from . instead of ../common.
4295 * Make-common.in: Remove. It's no longer necessary.

4367
4368 * run.c (main): Removed SH specific comments, so source is
