Comment(by johnmaddock):

 {{{
 BOOST_REGEX_NO_EXTERNAL_TEMPLATES did indeed help! All tests passed.
 Thanks! What does this mean then? ;)
 }}}

 It means it might work, or it might not!

 Normally the regex library instantiates the most commonly used templates
 in the library - as this speeds up compilation times no end - as well as
 reducing binary sizes.  Defining BOOST_REGEX_NO_EXTERNAL_TEMPLATES
 disables this, so the same templates end up getting instantiated in both
 the dll and the application.  Frankly if this doesn't work though, then I
 do wonder whether there isn't some hidden bug in gcc relating to sharing
 template instances across dll-boundaries :-(

 I will try and investigate some more though.

 {{{
 about your other problem - I managed to install on Win7
 with no troubles whatsoever following those instructions.
 }}}

 Sigh... for me not only does gcc crash and burn when I try and compile a
 hello-world app... it actually managed to bring down my whole machine :-(

 Cheers, John.
