The GNU make configure script currently doesn't enable high resolution file 
timestamp support for the Mac OSX platform.  However, nanosecond file 
timestamps are available, they're just stored in a different location in the 
'struct stat' structure used by the stat() API call (st_mtimespec.tv_nsec 
instead of the usual st_mtim.tv_nsec).  This patch updates configure to detect 
the availability of high resolution file timestamps for Mac OSX and use them 
within GNU make.  The patch is based on the latest GNU make sources from the 
CVS repository.
