4666 autoconf. If HAVE_UNISTD_H is defined, include unistd.h to get

4668 system.
4669

4671
4672 * Makefile.in (libcommon.a): Delete.
4673 (callback.o,targ-map.o): Delete, moved to Make-common.in.
4674 (gentmap,targ-vals.h,targ-map.c): Likewise.

4690 comments and single quotes. Fixes a problem found on hpux.

4699 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
4700 targ-map.o, and run are built. They are now built in the
4701 individual simulator directories, taking sources from ../common as
4702 necessary. This replaces the merging of libcommon.a into
4703 linsim.a, which was problematic for the WinGDB build process.
4704 * run.c: Include config.h from . instead of ../common.
4705 * Make-common.in: Remove. It's no longer necessary.

4777
4778 * run.c (main): Removed SH specific comments, so source is
