* Revision 1.2 2006/11/01 11:24:49 piru
* 2006-11-01 Harry Sintonen <sintonen@iki.fi>
* * Fixed ixemul and ixnet library open to check for AllocSignal()
* failures.
* * Disabled SetExcept() optimization until GDB issue is sorted out.
*
* Revision 1.1.1.1 2005/03/15 15:57:09 laire
* a new beginning
*
* Revision 1.3 2004/08/14 04:09:50 henes
* fixed some amitcp assign references
*
* I note ixnet is lacking error checking... I see some AllocSignal are not checked.
* Also some other stuff...
*
* Revision 1.2 2000/06/20 22:17:10 emm
* First attempt at a native MorphOS ixemul
*
* Revision 1.1.1.1 2000/05/07 19:37:46 emm
* Imported sources
*
* Revision 1.1.1.1 2000/04/29 00:44:34 nobody
