It appears GCC 3.x no longer supports the

thunks are being used?

I seem to recall one of the sore spots for us on Dawrin was getting good

Fortran was a particularly messy because some compilers didn't supply a linkage

through a qualified pointer is well-defined and that the usual qualifier
rules apply to that access.
