const uint64_t initialization problem

[Mike - EMAIL IGNORED]

On FC4 with g++ (GCC) 4.0.2 20051125 (Red Hat 4.0.2-8):

   unsigned long long int  mask = 0x003fffffffffffff;
   const uint64_t          mask = 0x003fffffffffffff;
   const uint64_t          mask = static_cast<uint64_t>(0x003fffffffffffff);

all result in:

   error: integer constant is too large for 'long' type

I workaround with:

   const uint64_t    mask = (0x003fffff << 32) | 0xffffffff;

Is this as expected?  Is it fixed in a later version?

Thanks,
Mike.
