Sorry, my fault, these are my first steps in MinGW, I used VC++ 6.0 'til now...
I tried it again, it's only a difference of 7 secs. I forgot after switching from Eclipse to Code::Blocks the wxWidgets libraries have also been recompiled by myself (and Code::Blocks uses). Therefore I suppose the new libraries seem to be the problem right now.
Again that's strange, but maybe this is a topic for another discussion board.

Or can you give me a hint to speed up gcc? About 2 minutes compilation and linking time for a simple
frame demo I used for testing is rather slow (in comparison to VC). Of course I can use the release
version of the libraries, but even that is far beyond VC with debugging information...
Nethertheless, thx for the reply
