I have compiled the stlport with "/Zc:wchar_t"(I also try /D "_MBCS" and /D"_UNICODE") since the library date_time need it when using stlported, switching "
on" and " off" dll file compiling all fails.
OK I've been able to reproduce that with STLport-4.6.2, the following patch will let the regex dll build with STLport and /Zc:wchar_t. John.
