I have seen a version of stdint.h for MS VC++ on the internet but I'm not sure of the quality or how portable it is between the different versions of VC++.
I already made that mistake for you. I hate see you write a lot of code
only to have to go back an fix it to accommodate VC++.

I knew that was coming:). Unfortunately, I can't see not supporting for
the foreseeable future. I'll sure be glad when that future arrives
though. I think stdint.h is part of the ISO C99 spec. Ten years later
and Microsoft still can't make an ISO C compliant compiler.

Yes, but you may what to use CMake to perform a compiler check to make
sure long long is actually 64 bits. Otherwise, you may run into some
unexpected surprises. wxUint64 is defined in wxWidgets so that may save
you some grief.
