Peter,

That is an excellent idea.  I'll look into a mechanism to check for DLL
names that conflict with what is in \windows\system32 and at least report
them to the user as an issue.

This is an issue for FWTools, and will also affect OSGeo4W which uses a
similar approach and thus be quite sensitive to conflicting DLLs.

Best regards,
