What symbols? If it's complaining about C runtime stuff, then most likely
you need to change you code generation options (STLPort doesn't support the
single threaded runtime options by default, and you probably need to use the
debug runtimes in debug mode as well, using the debug-dll /MDd option is
always a safe bet).

Also make sure that you have disabled auto-linking to regex by defining
BOOST_REGEX_NO_LIB as a project level define.

Just build all the libs/regex/src/*.cpp files into a static lib, the dll
version will probably only link if you build with /Zc:wchar_t
/DBOOST_REGEX_DYN_LIB=1, however you will then be able to use it
irrespective of whether your code uses /Zc:wchar_t or not.  Oh, and when you
build with STLPort, building with /Zc:wchar_t probably isn't supported (by
STLPort that is), so you *may* not be able to build regex as a dll in that
case unless you are using STLPort's iostreams (which I know does work).

Oh and someone told me recently that STLPort without it's own iostreams
doesn't work properly with VC7 (and 7.1?).

Whew :-/
