I'm not sure if this helps, but QueryPerformanceCounter could be
a source of semirandom 64-bit integers. It returns the processors
running time in nanoseconds. I'm not aware of anything, which returns
really random values.
On Windows itself you could use the CryptAcquireContext, CryptGenRandom
and CryptReleaseContext. I think that doesn't work on WinCE though.
