It seems to me that you are overcomplicating things. The whole idea of the
Qt SDK is that you have *everything* you need to build a Qt application. On
Windows, this includes a patched version of MinGW which does come with a
make:

Well, for me (i.e. not a Cygwin environment, but a *pure* Windows
environment), the execute bit is not relevant at all (not least because it
doesn't exist in a *pure* Windows environment).

I believe you are wrong (see above), but nevermind for now. I will be in
Auckland from Monday and for a month, so we can have a look at it next week
before your allocated CellML time runs out...
