A ((long long)fcp)++ is not valid C, and the C/iX compiler won't
accept it.  The operand of an increment operator must be a
modifiable lvalue.

If you want to use a cast to force an increment operation to act
on all 64 bits of a long pointer, the following should do the
trick:

     (*(long long *)&fcp)++
