+*abort.c - abort a program by raising SIGABRT
+*
+*	Copyright (c) 1989-1992, Microsoft Corporation. All rights reserved.
+*
+*Purpose:
+*	defines abort() - print a message and raise SIGABRT.
+*
+*Revision History:
+*	06-30-89  PHG	module created, based on asm version
+*	03-13-90  GJF	Made calling type _CALLTYPE1, added #include
+*			<cruntime.h> and fixed the copyright. Also, cleaned
+*			up the formatting a bit.
+*	07-26-90  SBM	Removed bogus leading underscore from _NMSG_WRITE
+*	10-04-90  GJF	New-style function declarator.
+*	10-11-90  GJF	Now does raise(SIGABRT). Also changed _NMSG_WRITE()
+*			interface.
+*	04-10-91  PNT	Added _MAC_ conditional
+*	08-26-92  GJF	Include unistd.h for POSIX build.

+*void abort() - abort the current program by raising SIGABRT
+*
+*Purpose:
+*	print out an abort message and raise the SIGABRT signal.  If the user
+*	hasn't defined an abort handler routine, terminate the program
+*	with exit status of 3 without cleaning up.
+*
+*	Multi-thread version does not raise SIGABRT -- this isn't supported
+*	under multi-thread.
+*
+*Entry:
+*	None.

+*Exit:
+*	Does not return.
