-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I noticed this, thanks to cygwin 1.7's improved QoI ctype.h header. (Hmm, maybe I should file a glibc bug that the Linux ctype.h should offer the same compiler warning when passing a char instead of an unsigned char to the ctype macros.) - -- Don't work too hard, make some time for fun as well!
