I know, that's why I said "run MSYS and type" ;). configure is a Linux
shell script and hence doesn't work in DOS. That's the whole reason why
we need MSYS in the first place.

That's certainly the better option. It may work with mixed directories,
because MSVC and mingw are using different intermediary file formats
IIRC, but I certainly wouldn't count on it ;).

Yep, there it is. I was expecting something like that, happened to me,
too ;).
What you did is a working solution, but not really optimal. The proper
way of doing it would be following step 4 (and possibly 5) of
http://techbase.kde.org/Projects/KDE_on_Windows/Installation#Summary_of_Steps
which will most likely be pointing towards the msvc version of the KDE
libs (if you followed the wiki instructions when setting up msvc).

As for the problem with compiling: Googling reveals that this is also a
well-known problem and apparently a bug in the Qt include files. There
is a workaround posted at http://www.itworld2.com/qtcompilation.aspx
(scroll to the very bottom of the page) which unfortunately involves
hacking the source code again (I hoped to get rid of that ;)).

Some little extra info about the problem: For some reason I don't quite
understand, the Qt sources include some definitions that are also
included in the windows header files. Apparently (some of) these
declarations don't match, which leads the compiler to complain if both
are used simultaneously (as is the case in TW). In fact, there are two
different versions in the Qt header files from which one is chosen based
on certain circumstances (e.g. the compiler that is used). In this case,
it seems that the wrong one is chosen. That's why the workaround at the
link above simply comments that wrong one, thereby forcing the compiler
to use the right one.

I hope this workaround does what it's supposed to do (and doesn't
introduce further inconsistencies).
