*
*Revision History:
* 06-06-89 PHG Module created, based on asm version
* 03-07-90 GJF Made calling type _CALLTYPE2 (for now), added #include
* <cruntime.h>, fixed compiler warnings and fixed the
* copyright. Also, cleaned up the formatting a bit.
* 07-24-90 SBM Removed '32' from API names
* 09-27-90 GJF New-style function declarators.
* 12-04-90 SRW Changed to include <oscalls.h> instead of <doscalls.h>
* 12-06-90 SRW Added _CRUISER_ and _WIN32 conditionals.
* 01-16-91 GJF ANSI naming.
* 04-10-91 PNT Added _MAC_ conditional
