Hi,

It appears GCC 3.x no longer supports the
-fvtable-thunks option. Is gcc 3.x using thunks by
default for its vtable format? Also, can the
_G_USING_THUNKS macro no longer used to determine if
thunks are being used?

the updated C++ ABI always uses thunks. http://www.codesourcery.com/cxx-abi/

There is no _G_USING_THUNKS macro (any more).
