In general I believe that unsigned char* makes much more sense than a
signed char.  However most Posix function expect char * and most
compilers default to signed for char.  One major problem I encountered
over the years are C libs not implementing the isfoo() suite correctly
(e.g. HPUX).  So you have to use either unsigned char * or cast to
that before using any of these functions or you will pretty sure get a
SEGV.

casts are only required very rarely today since we now have the void*.
