Yes, I've noticed this too. Perhaps there are reasons - parts of it
needed in early startup? Is there a problem with libgcc linked in
statically? Is it supposed to make a difference from the symbol
scope POV?

Ah yes, and pulled up, as a bugfix for mozilla on ppc.
Isn't there -nostdlibs if one wants the standard libs to be left out?
With c++, libstdc++ is still linked in regardless of -static, so this
looks more like a hack.

The mandrake distribution I tried does only have a static libgcc.a,
as we do. So the example I quoted in my last mail will link in these
runtime functions statically into the object to be loaded.
