Yes, it wouldn't put the files in the right place.  These settings are  
used on Mac OS X and it works.  One thing that might make sense is to  
not set prefix in ./configure but only when running make.

--no-undefined seems fine for now, but my guess is that it'll bite in  
the long run.

That's an odd one.  The auto-builds are run in the msys sh, see  
scripts/auto-build/run-automated-build.bat:

C:\msys\1.0\bin\sh.exe --login -i -c /home/pd/auto-build/pd-extended/ 
scripts/auto-build/run-automated-builder
