its a megamax C problem, uCsh is using the Force call to 'steal' i/o 
handle 1 (stdout) and force it to a file, this works fine as long as 
the 'redirected'  program only uses Fwrite to do the output. sadly
the printf routine in megamax C does not, hence the the 2 bombs.

the worst news is that there is no fix for it (except from Megamax
hint...hint...) i had to leave redirection out of uEmacs 3.7 because
of it. i spoke to some people at atari about this and they were not 
sure that DRI C's printf would fare any better.
