OK. I'd tend to favor more-generic names, but I can't think of better ones
right now.

These changes are all acceptable, but please make them carefully in the
RC_1_28_0 branch.

Yes. Sorry I lost track of this, but you now have CVS write permission.
Listen, take a look at tools/build/index.html and see how the current state
of gcc-nocygwin-tools.html relates. There should be no instructions for
building boost (especially since the name of the jam executable is now
"bjam"). Also, the first sentence should be changed accordingly. Also,
there should be a prominent reference section about configuration variables
in the format used for gcc-stlport-tools.html, with a link to that page
(because that's the toolset being extended).
