Folks,

Well, after a bit more investigation it appears that QGIS does *not* depend
on the GEOS C ABI (I checked a few qgis dll's with depends.exe to see what
they use).  I have uploaded a GEOS 3.2.2 package to the test environment
and very very briefly confirmed that mapserver, gdal and qgis seem to still
be working.  I'd appreciate some testing from others if convenient.

Best regards,
