fgetc() returns an int. Fix process_config_file() to store the result in an int, so that comparisons against EOF succeed. Previously, If "char" defaulted to unsigned (which may be true for armhf), then when fgetc() returned -1, it would be truncated to 255 when stored in the char, and then zero-filled rather than sign-extended when comparing against EOF, which would then fail.
