OK, what is 'install' doing for us that 'cp' and 'chmod' would not
already do? The following patch reduces the 'gmake install' in
/src/include from 8 seconds to 0.8 seconds.
Oh, and for testing I use a sourceforge shell farm account, and a HP
testdrive shell acount that gives me access to almost every operating
system.
