Revision 1.4 1998-05-22 00:39:25 peter
* go32v1, go32v2 recompiles with the new objects
* remake3 works again with go32v2
- removed some "optimizes" from daniel which were wrong
Revision 1.5 1998-07-15 16:10:35 jonas
* new mouse uni
Revision 1.3 1998/04/05 13:56:54 peter
- fixed mouse to compile with $i386_att
+ linux crt supports redirecting (not Esc-codes anymore)
Revision 1.2 1998/03/26 12:25:22 peter
* integrated both mouse units
Revision 1.1.1.1 1998/03/25 11:18:41 root
* Restored version
Revision 1.4 1998/03/24 15:53:12 peter
* cleanup and doesn't give warnings when compiling
