To avoid further surprise, I will add an L after 640 or 480.

I know Jeff probably use djgpp (so 32-bits int), but this is just in case.
It doesn't cost a lot of typing or storage, and it can be *very* big help 
for someone who tries to port this to plain DOS (where 640*480*2 is -40960,
converted to 24576 when casted to size_t)...

OTOH, it can be spurious on a plateforme where long are 64 bits.
