modification history
--------------------
01e,29aug01,hdn  added support for streaming SIMD exception.
01d,29may94,hdn  removed I80486 conditional.
01c,08jun93,hdn  added support for c++. updated to 5.1.
01b,26mar93,hdn  added a new vector for 486.
01a,28feb92,hdn  written based on TRON, 68k version.
