What a great publicity for RHIDE!! :-)
RHIDE speeds up your programs!! :-))

But I'm sorry to say that is has nothing to do with RHIDE. :-(

It is a phenomenon of DJGPP!!
To check it, simply run the test program from _ANY_ other
DJGPP program. For instance start bash and then run the
clip.exe or do

redir clip.exe

and you will see the same speedup. But please do not ask me
for the reason, I don't know (and have not the time to
search for it).
