And exactly that, as I tried to point out, happens all the time in KDE, since 
most of the targets in KDE are either shared libraries or kdeinit modules, 
both of which require -fPIC.

Andras' mail on kde-core-devel is just another example of that as he 
hits /exactly/ this problem. Either we disable STATIC (and break the build) 
or we add -fPIC to the build flags (as suggested in my initial patch in this 
thread). My vote is on the latter, but ultimately I don't care as long as we 
solve it :)
