Hi all,

I'm trying to build a Python extension that provides access to some facilities 
used by an application. These facilities are currently packaged as static 
libraries and linked into the app executable.

But I find I can't use the static libraries in the extension, because that's a 
shared library, and so requires (target is amd64) the code in the static 
libraries to be built with -fPIC, which currently it isn't.

As far as I can see, there's no way to flag code in a static library as 
potentially shared. I don't want to convert all the static libs to shared in 
the app. So I think my only option is to add -fPIC to CFLAGS.

Have I missed any cunning better method?
