** 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.
**

** Author: Lawrence Hardiman <larryh@netscape.com>.
