MinGW32 is not the best gcc on Windows, they are behind other variants in
terms of API, exceptions, threads and other minor features.
I recommend using mingw-w64 directly or, if you want an easier
installation, mingw-builds (which is mingw-w64 with a fancy installer)
http://sourceforge.net/projects/mingwbuilds/
http://mingw-w64.sourceforge.net/
That being said, Visual C++ is by far a better compiler than MinGW on
Windows, especially on Win32.
How can I build Wt by MinGW instead of M$ Visual C++ compiler?

If you want a full build with all the dependencies, the easiest way would
probably be to adapt winstng:
http://www.gitorious.org/winstng
If using MSYS, the adaptations should be quite simple. OpenSSL will
probably be the "hardest" (you'd need to read the OpenSSL Win32 build
instructions).
One of this days I will put together a final "pack" step in that and try to
convince Emweb to redistribute a ready-to-go binary SDK :-)

In general you cannot mix the output of different compilers because they
produce a different ABI, not only on Windows but on all platforms and all
compoilers.
An special case is the Visual C++ 6.0 ABI, which has become (de facto) as a
sort of "universal ABI" on Windows: whatever you compile to Visual C++ 6.0
ABI can be used in a later version of Visual C++ and MinGW (and probably
others). This is what most open source projects which are cross-compiled
for Windows from Linux do.
What you want to do (link Wt application built by MinGW with Wt libraries
built by VC++) is impossible to do AFAIK:
- You cannot compile Wt with Visual C++ 6.0 (too much templating)
- AFAIK You cannot tell Visual C++ to produce Visual C++ 6.0 ABI
- MinGW will not take in Visual C++ 2003, 2005, 2008, 2010, 2012 or 2013
ABI
The opposite would be doable, though: compile Wt with MinGW, then your
application with Visual C++ (any version). But it's not what you want to do.
Hope that helps.
