At least that's a simple fix ;-)

For the limited use of build.jam it does really matter. Just as long as it
links them with the .o, does it? In Boost.Build proper the extensions are
already handled correctly, as the SUFOBJ, SUFLIB, are all there.

Writting VMS alternatives would be nice though :-)

Keeps a record of which directories we already have asked to get created so
that we don't attempt to make a directory multiple times.

Yes. It's a new language construct used in BBv2.

Differences to the CVS state would be easier to integrate but I could manage
1.30.2 diffs. Posting them to this list will ensure that I pay attention to
them... as sending them directly to me there's a chance I'll miss is because
of e-mail filtering on my side.
