Relocations?  Aren't those for ill-designed code that has some code in
it that can't execute at the position it's loaded, so is moved
elsewhere?  Proper libraries should be pure PIC.

AFAIK, libraries are mapped in with mmap(), so if they're truly pure PIC
libraries (as they should be), there shouldn't be relocations.  Those
that have them, well. . . somebody needs to boot whoever in the head.
Personally I want a gcc that I can set to hard error when it generates
code that will cause a relocation when linked, to help with eliminating
these nuisances.

    Creative brains are a valuable, limited resource. They shouldn't be
    wasted on re-inventing the wheel when there are so many fascinating
    new problems waiting out there.
