Eric,

I've tried to get boost build to create a preprocessor output file
without success.  I've had to use make to do that; consequently, I've
had to have 2 methods of building.  Have you been able to
create some boost build v2 rules that produce the preprocessor
output?  If so, could you publish it.  I did pose this question to
the boost build list:

http://article.gmane.org/gmane.comp.lib.boost.build/14930

but got no answer there :(

TIA.
