So has Mac OS X (darwin) but this did not keep libgcc from being a static
library until Apple started to use GCC 4.0.

You mean like embeded targets.  Though for embedded targets usually you
only want the version for processor and don't care about anything else.

Uli you keep forgetting about other OS which don't use elf (like Mac OS X),
though for Mac OS X, it is easier to support this as the way mach-o handles
fat binaries, you only really need one libgcc which contains the functions
for all of subprocessor types.
