*
*Revision 1.5  2005/07/09 23:15:04  ddiego
*merging in changes from devmain-0-6-7 branch.
*
*Revision 1.4  2005/01/08 20:52:47  ddiego
*fixed some glitches in osx impl.
*
*Revision 1.3.2.2  2005/05/08 19:55:32  ddiego

*existing code in the framework that made use of the old style var arg
*functions.
*
*Revision 1.3  2004/12/01 04:31:41  ddiego
*merged over devmain-0-6-6 code. Marcello did a kick ass job
*of fixing a nasty bug (1074768VCF application slows down modal dialogs.)
*that he found. Many, many thanks for this Marcello.
*

*This checks in a bunch of changes to the FoundationKit for OSX
*porting. The thread, mutex, semaphor, condition, and file peers
*have all been implemented and tested. The file peer could be improved
*and needs search functionality. The locale peer is only partially
*complete, but the functions will return values. The unicode transition
