No, it's not, but the backend is not compiled as position-independent.

I don't doubt that, but out of curiosity, considering that everyone else 
is using libtool, and libtool always uses -fPIC, what kind of impact 
does this *really* have?

That would certainly work, but is that the kind of interface we want to 
offer?  In the extreme case, a module could end up redefining a great 
deal of the shared library knowledge that it was supposed to not have 
to care about.
