Did you see the part of the captures docs that reads:

"Unfortunately enabling this feature has an impact on performance (even if 
you don't use it), and a much bigger impact if you do use it, therefore to 
use this feature you need to:
  a.. Define BOOST_REGEX_MATCH_EXTRA for all translation units including the 
library source (the best way to do this is to uncomment this define in 
boost/regex/user.hpp and then rebuild everything.
  b.. Pass the match_extra flag to the particular algorithms where you 
actually need the captures information (regex_search, regex_match, or 
regex_iterator). "
Note that normally most people will *not* need this feature however.

Hmm, seems to work OK for me with VC8-Express, at the risk of stating the 
obvious you may need to build the file once and then wait for Intellisense 
to update before it becomes available however.

HTH, John.
