#3 Conflicting declarations of variable pinbuf

[Michael Tautschnig]

Hi,

While building your package using our research compiler infrastructure we noticed the following conflicting declarations:

./arcio.c:extern char *pinbuf; /* general purpose input buffer */
./arc.c:u_char *pinbuf, *pakbuf, *outbuf, *outend;

Interpreting the buffer both as signed and unsigned char will result in undefined behaviour.

Best,
Michael

The buffer is not used in arc.c, so there is no ambiguity in usage.
