This might be make or the disastrously slow split-for-gcj shell
script.  However, I was a little reluctant to check in my patch at
http://lists.gnu.org/archive/html/classpath-patches/2005-08/msg00145.html
that replaces a shell script with an Awk program, because at lest
shell scripts are portable everywhere.  Even on a fast machine
(Athlon64 3200+) this patch shaves a minute from the build time.
