Are you sure that that's defined for all translation units that use or
implement Boost.Regex?

It's in "boost/regex/v3/regex_library_include.hpp".

I know I had some kind of problem with the above-mentioned header
generated the wrong library name when I first started using
Boost.Regex so I disabled the header by defining its guard macro
before including "boost/regex.hpp".  However, I removed that just
now and didn't have any problems.

Have you created your own project definition which uses a different
library name?  It's probably easier just to use the makefile
(vc6.mak) in Visual Studio.  You can do this by selecting
"Insert Project into Workspace", selecting "vc6.mak" from the build
directory, and thus creating a project that calls nmake on the
makefile.  Then you just need to edit the project settings to
specify what the target names are for each configuration.
