I can't wait.  Here is a short one.  Compile it as

  gcc -fpic -c got.cc 

and you should get the GOT warning.  You can play with it.  If you
define constructor foo::foo() as an inline function too, or, remove
the "inline" keyword from definition of foo::bar(), you can get rid of
the GOT warning.  Anyone?

Thanks a lot!!
