Hmm.. you're right. I've corrected the warning message.

This is most likely because some generator refused to work. I'm not sure why, 
but maybe you can find out by running bjam with --debug-generators options.

Maybe, it's possible to use a trick: there's "setup" parameter. When it's not 
specified, the default vcvars32.bat is used. I think it's possible to allow 
passing empty string for that parameter, and make sure no calls to setup 
scripts are generated in that case. This should be simple ;-)

Thanks for catching. I've removed it.
