INCLUDE_CCTYPE not supported error

[thomb]

Why do I get this error when compiling code that uses the header?
dcmtk-3.6.8\ofstd\include\dcmtk\ofstd\ofstdinc.h(61,1): error C1189: #error: "Macro INCLUDE_CCTYPE not supported anymore. Include <cctype> directly."

I see that I'm supposed to include <cctype> directly but having trouble figure out where.

I found the #define of INCLUDE_CCTYPE and will add the #include for <cctype> in that header file.

We have removed some compatibility code for ancient C++ compilers that did not support the C++98 standard. This has standard now been available for 25 years, so it is probably safe to exclude compilers that do not support <cctype> and require <ctype.h> instead.
