Ross Williams 7ed7014e14 Change getc return type from char to int32_t ...

The return type of `getc(3)` is a signed integer,
with negative values indicating an error. The changed
line stored the return value in an *unsigned* integer,
then tested it against a negative error constant, so
the error condition would never be detected. This
also results in a warning on GCC 10.
