 CONST 


 not all constants are necessarily available on all platforms
 ones marked * portable * are perhaps more portable
 ones not marked * portable * are perhaps less portable, but
 really, the marking means used by m3core/libm3 and/or defined in
 Uconstants.c without an #ifdef, or portable so far.
 Lack of a marker really means not used by m3core/libm3, but present
 here for compatibility with older files or for courtesy in case
 anyone uses them, it fairly cheap to provide all constants
