PATCH: two issues with int -> char casts.

Below is a patch for two instances where the output of getc() is
assigned to a char and subsequently compared to EOF (the integer -1).

This issue was caught by GCC on the ARM architecture, which has
unsigned chars.  (So the EOF comparison always fails.)


Thanks,
