I need to read, create combinations using OR (|), and fprintf large numbers
like 8589934592 (2 to the 33rd and up to 2 to the 50th). I am using the HP
UNIX cc compiler. Obviously, unsigned long doesn't do the job. Are there
any types that support bitwise operations that can handle these sizes?
Thanks.

Some compilers have a long long type, soon to be sanctioned in C9x.
Other than that, you can use a multiple-precision math library such as
GNU gmp at ftp://ftp.gnu.org/pub/gnu.
