This can be fixed with #ifdef for mingw. MSVC has a _tradition_ of using lib 
names without "lib" prefix, and I guess with is not bad. I used this on KDE3 
with no problem and the code (that I ported) reflects this idea.

I'd be about to drop .la files usage compeltely in KDE4, on win32, then on 
UNIX. Installing wil be easier, and faster.

Developers: Please tell me how do you like this? I can most likely provide a 
patch.
