Revision 1.168 - (hide annotations) (download) (as text)
Tue Jun 15 11:54:33 2004 UTC (15 years, 2 months ago) by wingman
Branch: MAIN
Changes since 1.167: +10 -6 lines
File MIME type: text/x-chdr
* Fixed all current compile warnings
* Terminal mode was entered even if there was no -t command line arg.
  Currently this is fixed with a global int symbol, but imho we might
  need to find a better way to deal with accessing command line args
  in modules (and mapping them back to the core).
