compiler requirements?

I am having issues compiling with this with gcc-4.8

my config line is CC=i586-mingw32-gcc CXX=i586-mingw32-g++ cmake ../

but when i run make I get errs from the src.

MemoryModule.c:112:58: error: ‘uintptr_t’ undeclared (first use in this function)
                 section->Misc.PhysicalAddress = (DWORD) (uintptr_t) dest;
