It's possible to add features specific to your toolset only by putting the
"feature" declaration in your toolset file.

As far as I know that should work. cxxflags is a fre feature, which means
that it can accept any value you give it, especially compiler flags ;-) Are
you getting an error? Or is it strange behaviour of some other kind?

We've had long conversations about pch and pdb files ;-) In fact we already
generate *.pdb files for all links. If you want to add *.pch files take a
look at the "Link-action" rule in msvc-tools.jam and how it uses the
"vc-set-pdb-file" rule.
