* 03/02/96 Jes Sorensen, Andreas Schwab, Roman Hodek:
17
+
* Fixed some nasty bugs, causing some horrible crashes.
18
+
* A: At some points, the sum (%0) was used as
19
+
* length-counter instead of the length counter
20
+
* (%1). Thanks to Roman Hodek for pointing this out.
21
+
* B: GCC seems to mess up if one uses too many
22
+
* data-registers to hold input values and one tries to
23
+
* specify d0 and d1 as scratch registers. Letting gcc
24
+
* choose these registers itself solves the problem.
