 ** testll.c -- test suite for 64bit integer (longlong) operations
 **
 ** Summary: testll [-d] | [-h]
 **
 ** Where:
 ** -d       set debug mode on; displays individual test failures
 ** -v       verbose mode; displays progress in test, plus -d
 ** -h       gives usage message.
 **
 ** Description:
 ** lltest.c tests the functions defined in NSPR 2.0's prlong.h.
 **
 ** Successive tests begin to depend on other LL functions working
 ** correctly. So, ... Do not change the order of the tests as run
 ** from main().
 **
 ** Caveats:
 ** Do not even begin to think that this is an exhaustive test!
 **
 ** These tests try a little of everything, but not all boundary
 ** conditions and limits are tested.
 ** You want better coverage? ... Add it.
