Comment (by anonymous):

 Using your command line and the test program I posted above the output
 message I see is:

 {{{Linking to lib file: libboost_regex-vc100-mt-sgd-1_49.lib}}}

 which is the static regex lib as expected/required.

 As Steven has correctly pointed out (my bad) BOOST_DYN_LINK is an internal
 macro set just before including the auto-link machinery.  For regex it is
 only set if BOOST_REGEX_DYN_LINK or BOOST_ALL_DYN_LINK are defined:  these
 are user settable macros, we don't set them.

 Try adding:

 {{{
 #if defined(BOOST_ALL_DYN_LINK) || defined(BOOST_REGEX_DYN_LINK)
 #error "Oops"
 #endif
 }}}

 Right before you include boost.regex in your code, my guess is the error
 will be triggered, and then you just have to figure out where those
 defines are coming from.

 HTH, John.
