CVS: winex/libs/ptmalloc3/sysdeps/generic atomic.h, NONE, 1.1 malloc-machine.h, NONE, 1.1 thread-st.h, NONE, 1.1

Subject: winex/libs/ptmalloc3/sysdeps/generic atomic.h,NONE,1.1 malloc-machine.h,NONE,1.1 thread-st.h,NONE,1.1Update of /var/lib/cvsd/cvsroot/winex/libs/ptmalloc3/sysdeps/generic
In directory agravaine:/tmp/cvs-serv6141/libs/ptmalloc3/sysdeps/generic

Added Files:
	atomic.h malloc-machine.h thread-st.h 
Log Message:
- add a new memory allocator based on ptmalloc3 and make it the default (at least for now for testing)
- to disable, add "NewAllocator"="N" to the [Wine] section of your config file
