[macppc, arm*] Fix an infinite loop in games/qqwing

[Charlene Wendling]

Hi,

On my macppc machine, i can create an infinite loop just by doing:

  $ qqwing --generate | qqwing --solve

The looped getchar(3) call never reaches EOF on unsigned char archs.

The below diff fixes that issue.

OK?

Charlène.
