- * ++roman (07/09/96): implemented signal stacks (specially for tosemu on
- * Atari :-) Current limitation: Only one sigstack can be active at one time.
- * If a second signal with SA_ONSTACK set arrives while working on a sigstack,
- * SA_ONSTACK is ignored. This behaviour avoids lots of trouble with nested
- * signal handlers!

+ * 03/02/96 Jes Sorensen, Andreas Schwab, Roman Hodek:
+ * Fixed some nasty bugs, causing some horrible crashes.
+ * A: At some points, the sum (%0) was used as
+ * length-counter instead of the length counter
+ * (%1). Thanks to Roman Hodek for pointing this out.
+ * B: GCC seems to mess up if one uses too many
+ * data-registers to hold input values and one tries to
+ * specify d0 and d1 as scratch registers. Letting gcc
+ * choose these registers itself solves the problem.
