   7 ** testll.c -- test suite for 64bit integer (longlong) operations
   8 **
   9 ** Summary: testll [-d] | [-h]
  10 **
  11 ** Where:
  12 ** -d       set debug mode on; displays individual test failures
  13 ** -v       verbose mode; displays progress in test, plus -d
  14 ** -h       gives usage message.
  15 **
  16 ** Description:
  17 ** lltest.c tests the functions defined in NSPR 2.0's prlong.h.
  18 **
  19 ** Successive tests begin to depend on other LL functions working
  20 ** correctly. So, ... Do not change the order of the tests as run
  21 ** from main().
  22 **
  23 ** Caveats:
  24 ** Do not even begin to think that this is an exhaustive test!
  25 **
  26 ** These tests try a little of everything, but not all boundary
  27 ** conditions and limits are tested.
  28 ** You want better coverage? ... Add it.
