Can you fix this?

I confirmed that QEPCAD isn't functioning for me locally on an armhf system
(Raspberry Pi).  I'll see if I can track down the issue.

I believe the issue was that QEPCAD was reading input using a `char`, and
occasionally checking to see if this was EOF, which is negative (-1).  But on
the failing architectures, `char` defaults to unsigned, so it was getting
255 instead of -1, and we ended up with infinite loops.

I'll upload a new version of the package containing a patch, which I confirmed
works on armhf, shortly.

Doug
