/* This module contains replacements for functions in ctype.h besides other
** functions. There is a problem with using ctype.h directly:
** The parameter must have a value of "unsigned char" or EOF.
** So on platforms where a char is signed, this may give problems or at
** least warnings. The wrapper functions below will have an "char" parameter
** but handle it correctly. They will NOT work for EOF, but this is not a
** problem, since EOF is always handled separately.
