Tweak to hints/machten.sh: stop t/lib/complex.t from failing

[p5sagit/p5-mst-13.2.git] / t / op / runlevel.t

#!./perl

##
## all of these tests are from Michael Schroeder
## <Michael.Schroeder@informatik.uni-erlangen.de>
##
## The more esoteric failure modes require Michael's
## stack-of-stacks patch (so we don't test them here,
## and they are commented out before the __END__).
##
## The remaining tests pass with a simpler fix
## intended for 5.004
