A bug in GNU spell

[Luca Saiu]

  Hi.

  I found a little bug in GNU spell 1.0. It's several time old but 
seems the latest version.
  I saw the misbehaviour (spell does not react to any command line 
argument or option including --help and --version, and hangs) happening 
on GNU/Linux PowerPC, and is due to the implementation-dependent 
signedness of the C char type; a char variable is compared with a 
constant which happens to be neagative (EOF), and the test always yields 
the same value because of the truncation due to limited width.

  The fix is really trivial: change the declaration from char into int.
  The lines to update are spell.c:162 and str.c:139

  Best regards,
