Summary: Latest Aztec bug fixes

Here you go, Netlanders--hot off the Aztec West Coast BBS, 1-415-339-2427.

/*
 *	Aztec C68K/Am PATCH program v 1.3 - 4/2/87
 *
 *	This program provides patches which fix bugs in the 3.4a version
 *	of the Aztec C68K system.
 */

/*
 *	1) A statement of the form: < array[index] op= > will sometimes generate
 *		incorrect code which will modify the wrong address in memory.
 *
 *	2) A multiplication/division/modulo operation involving CHAR types
 *		within a conditional statement generates incorrect code.
 *		(Patch fixed in v 1.2)
 *
 *	3) Some bit field operations used the "lsr" instruction instead of the
 *		"ror" instruction.
 *
 *	4) The abs() routine is incorrectly being detected by the 68881 code
 *		generation.
 *
 *	5) In AS, a null pointer is sometimes used.
 *
 *	6-9) Fix AddGList function in cXXX.lib.
 *
 *	10-13) Fix NewModifyProp function in cXXX.lib.
 *
