 377
 378         * simops.c: Rework code to extract arguments for emulated
 379         syscalls to handle 24bit pointers.

 382
 383         * configure configure.in Makefile.in:  Update to new configure
 384         scheme which is more compatible with WinGDB builds.
 385         * configure.in:  Improve comment on how to run autoconf.
 386         * configure:  Re-run autoconf to get new ../common/aclocal.m4.
 387         * Makefile.in:  Use autoconf substitution to install common
 388         makefile fragment.

 391
 392         * simops.c: Fix destination register for "mov (abs24),an".

 395
 396         * simops.c: "rts" adds 4 to the stack pointer.
 397
 398         * simops.c: Fix CF and CX computation for add instructions.
 399
 400         * simops.c: Leave the upper 8 bits alone for logical ops.

 405
 406         * simops.c: Don't lose the sign bit for "asr".

 409
 410         * simops.c: Fix overflow computation for "cmp" and "sub"
 411         instructions.
 412
 413         * simops.c: Use the right register for "jmp (an)" and "jsr (an)".
 414
 415         * interp.c (hash): Improve hashing for 3 byte instructions.
 416
 417         * simops.c: Fix extraction of 16/24bit immediates for some
 418         instructions.  "cmp" instructions only modify the PSW.
 419         Fix various thinkos when extracting register operands too.
