If it's not needed I agree there is no point in adding a VFP version

to the package.

Is there an easy way to tell if a shared library contains no FP?

Yes, I can't see anyway around this unless we decide all autobuilder

application will use shared libraries and don't bother with static

libraries. But that will probably upset too many people - or  am

I mistaken here?

My thoughts were to just build VFP libraries as they are needed

for now. i.e. if I build a VFP static application and that needs

several static libraries, I'd upload new versions of the libraries

with the static VFP versions as well.

Also as with all of this, if someone asks for a VFP build of a

particular library then that would be done.
