The tests/strings/21.cwctype.cpp source file fails to compile with these errors:

make: Target `all' not remade because of errors.

This is because the C/C++ preprocessor on Darwin distinguishes `#undef isdigit' 
and `#undef isdigit(x)' as seperate directives with different semantics.  Need 
to add directives for the latter form.
