WOW. This has made a massive difference to java compile times
on cygwin - jc1 is one or two orders of magnitude faster.
stat() is VERY expensive on cygwin. At present it opens each file
in a directory due to the differences between NTFS and unix file
systems. jc1 would take in excess of 1 minute per file on a P4
machine. Now it is less than a second per file.

I analyzed why building libjava (and presumably any other Java
program) took so long to build.
