Revision:	2.9
Committed:	Thu Jun 26 00:58:09 2003 UTC (20 years, 10 months ago) by schorsch
Content type:	text/plain
Branch:	MAIN
Changes since 2.8:	+2 -2 lines
Log Message:	Abstracted process and path handling for Windows. Renamed FLOAT to RREAL because of conflict on Windows. Added conditional compiles for some signal handlers.
