Simple question... I understand that you are trying to get a MinGW version
of the CellML API so that I can use it in OpenCOR on Windows. Now,
considering that I use Qt/C++ which comes with MinGW, I would imagine that a
first approach would be to try to build the CellML API with the MinGW
version shipped with Qt/C++? I appreciate that it might seem like a bit of
an overkill (I mean, installing MinGW + Qt just to build the CellML API),
but it might save you time in the long run. In fact, it might save me time
too later on!

?! Build a newer version of gcc?!

I use the version of MinGW which is shipped with Qt/C++ and the version of
its gcc is 4.4.0.

Sorry, I have no idea about this. I would have to find out. Please let me
know if you would like me to do that.

Well, yes, I do care otherwise, and unless I missed something, what's the
point of using the CellML API?
