Besides the toupper etc. vs. signed char issues, there is an upper
limit of char values defined in include/regex/regex2.h. For none MB
installtions, it is defined as:

#define OUT (CHAR_MAX+1) /* a non-character value */

where CHAR_MAX gives 255 for "char = unsigned char" platforms. This is
good. However it gives 127 for "char = signed char" platforms. So if
you have some none ascii letters greater than 128 on "char = unsigned
char" platforms, you will lose.

Changing above to:

#define OUT (UCHAR_MAX+1) /* a non-character value */

might help...
