Pattern 15.

In C99, a hexadecimal integer constant has type long long int or unsigned long long int if it is too large to fit in (unsigned) long int, but fits in (unsigned) int64_t is exactly 64 bits. –Karoly Horvath Mar 7 '12 at 18:34 Thanks...

We've come up with what we think is a reasonable solution using macros, but was curious to know if people could think of cases where this might fail or if there Please note we are trying to do this in a cross-platform, multiple compiler environment. #if ((ULONG_MAX) == (UINT_MAX)) # define IS32BIT #else # define IS64BIT #endif #ifdef IS64BIT DoMy64BitOperation() #else DoMy32BitOperation() I'm guessing MinGW is just making sure it's still the case and there're no surprises. However, int_least64_t and long long int are (as of C99) mandated by the standard and must have at least 64 bits (63 value bits + sign bit). –Daniel Fischer Mar 7 Visual Studio Compile 64 Bit Dll
