<cctype> is not part of the DJGPP project, it is part of the GCC port.  I 
wonder how come GCC maintainers didn't pay attention to this issue.

I wonder what happens with other C libraries.  Does glibc, for instance, 
define inline versions depending on __cplusplus?

You don't need to disable macros by #undef.  You could provide inline 
versions in <cctype>, for example.
