The complaint was the ?Megamax C? had problems with the following code
unsigned x;
while ((x=getchar) != EOF) {   ... }

the complaint was the it went into an infinite loop.
while if x was just an int everything was fine.

He gave an idea that it may have had to do with the
sign extending of char to int.

well the problem acctully is I believe (I don't
have or use magamax c so this is an educated guess)
if you look in STDIO.H you will see that
EOF is declared to be -1.
some c systems use -1 others use 0 i believe.
well the whole point is that -1 is legal and
SOMEWHERE in KR it says so you can have the fun
looking for the little blurb.  I seem to
remember it being in the second chapter and
never did see it in the definition if you
really want to find it.
