6509 * callback.c: If HAVE_CONFIG_H is defined, include config.h from
6510 autoconf. If HAVE_UNISTD_H is defined, include unistd.h to get
6511 appropriate definitions of read, write, etc. Add prototype for
6512 system.

6514Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
6515
6516 * Makefile.in (libcommon.a): Delete.
6517 (callback.o,targ-map.o): Delete, moved to Make-common.in.
6518 (gentmap,targ-vals.h,targ-map.c): Likewise.
6519 (run-autoconf): Delete.
6520 * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
6521 (common makefile fragment): Moved back into ...
6522 * Make-common.in: Resurrect.
6523 * configure.in (AC_LINK_FILES): Delete, unnecessary now.

6534 comments and single quotes. Fixes a problem found on hpux.
6535
6536Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
6537

6541 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in

6543 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
6544 targ-map.o, and run are built. They are now built in the
6545 individual simulator directories, taking sources from ../common as
6546 necessary. This replaces the merging of libcommon.a into
6547 linsim.a, which was problematic for the WinGDB build process.
6548 * run.c: Include config.h from . instead of ../common.
6549 * Make-common.in: Remove. It's no longer necessary.
