Maybe I got my configs confused, but I thought I tried that and when I did,
the link still came up with "unable to open boost_regex_vc7_mdid.lib".  I
had to add an explicit /nodefaultlib: to the link and explicitly include the
library I wanted to get an error-free link.

Ah - that's the piece I was missing.  I was hoping for a lib-free
configuration, for easier project maintenance (small project, only one
translation unit uses regex, etc).
