Hi,
Append "LL" to your constant:
0xFF00FF00FF00FF00LL
What must I do to be able to assign 0xff00ff00ff00ff00 to value1?

Or better (?) still: Append ULL to it, since it's unsigned. And if you need to support other compilers that don't use LL and ULL, you can use macros (as found in MAME):

#ifdef __GNUC__
#define U64(val) val##ULL
#define S64(val) val##LL
#else
#define U64(val) val
#define S64(val) val
#endif

and then use it like so:

U64(0xFF00FF00FF00FF00)
