PGPUInt64, PGPInt64
Find a 64-bit data type, if possible.
The conditions here are more complicated to avoid using numbers that
will choke lesser preprocessors (like 0xffffffffffffffff) unless
we're reasonably certain that they'll be acceptable.
Some *preprocessors* choke on constants that long even if the
compiler can accept them, so it doesn't work reliably to test values.
So cross our fingers and hope that it's a 64-bit type.
GCC uses ULONG_LONG_MAX. Solaris uses ULLONG_MAX.
IRIX uses ULONGLONG_MAX. Are there any other names for this?
