Hi Beman,

Please build yourself a new Jam and try again.

I believe I have fixed the line-length problem (jam was checking the
overall size of the command rather than the length of an individual
line) and also the showstopper problem you were having with testing.

Solving the testing problem required the introduction of a new rule,
RMOLD, which will cause a target to be removed if any of its
dependencies fails to build. The old FAIL_EXPECTED rule has been removed
(it was unused anyway).

There are several deficiencies in Jam's dependency handling which we
might want to address:
