2003-07-17 Richard Frith-Macdonald <rfm@gnu.org>
* Source/NSRunLoop.m: ([-acceptInputForMode:beforeDate:]) use the
NSThread method to sleep rather than re-implementing it.
* configure.ac: Check for nanosleep()
* Headers/Foundation/config.h.in: Add entry for nanosleep
* Source/NSThread.m: Use nanosleep if available.
2003-07-16 David Ayers <d.ayers@inode.at>
* config.make.in: Default to builing -baseadd on non *-gnu-*
