Christian-
Would you tell me which svn revision of mini you’re compiling, which version of MinGW you’re using, and how you generated the “MinGW generating specs from…” output in your original post? I’d like to get MinGW working, partly to look into your non-linking issue, but I’m running into MinGW issues which you seem to have avoided.
Also, if you’re up for setting up cygwin, I’m working on instructions for compiling using cygwin instead. I know it’s possible, since I’ve done it; I just need to recreate the steps
