I fear I may not have explained this well.

On the Solaris systems I have access to, I find no system include file
that defines "ULONG_LONG_MAX".

There are defines for ULONG_MAX which is equivilent to the value that
ULONG_LONG_MAX is, but only when the system is being compiled on
an "_LP64" (ie x86_64) system.  When the system is 32-bit, ULONG_MAX
defaults to a typical max value for a 32-bit unsigned int.

That help?
