Note the +* general grouping of only OS-dependent definitions +* followed by OS and processor dependent definitions. +* 02-25-91 SRW Move _JBLEN definition back to setjmp.h [_WIN32_] +* 04-09-91 PNT Added _MAC_ definitions +* 05-09-91 GJF Restored _JBLEN definitions. Also fixed the macros +* defining the target processor so both Stevewo's stuff +* and mine would work. +* 05-13-91 GJF Changed _CALLTYPE1 and _CALLTYPE4 to _cdecl for +* Cruiser (_CRUISER_). +* 08-28-91 JCR ANSI keywords +* 11-01-91 GDP _JBLEN back to setjmp.h, stdarg macros back to stdarg.h +* 03-30-92 DJM POSIX support. +* 08-07-92 GJF Revised various macros. +* 09-08-92 GJF Restored definition of _MIPS_ (temporarily). +* 11-09-92 GJF Revised preprocessing conditionals for MIPS. +* 01-09-93 SRW Remove usage of MIPS and ALPHA to conform to ANSI +* Use _MIPS_ and _ALPHA_ instead. +* 02-01-93 GJF Removed support for C6-386. +* +****/ + +#ifndef _INC_CRUNTIME + +/* + * Some CRT sources have code conditioned on _MIPS_.
