The .hidden changes to mklibgcc.in gives me nearly 1000 unexpected C++
failures for i386-unknown-netbsdelf1.5ZA (and from reading the gcc-
testresults list it looks like more targets have problems.)
About 900 of the failures comes from crtbegin.o not finding
__register_frame_info. I tried to fix this by not hiding symbols
having "register_frame" in their name, but there are still > 100
failures where the run-time link-editor complains that libstdc++.so.4
has an undefined symbol _Unwind_RaiseException...
I have no idea how to fix this since I don't understand how this
change is meant to work (as I understand the ".hidden" directive,
it is supposed to hide the symbol from other components. So I
cannot see how this could work...)
