Does anyone know of widely-used programs that depend on the type
`char' being signed?  That is, how many programs would break if
`unsigned char' and `char' were the same type?

One should not depend on chars being signed, but not all programmers
are reluctant to use implementation-dependent features with abandon.

Thanks for your comments.
