remember linkage of a function type (3)
This version of the patch, with -fpermissive and without -Werror, bootstraps
gcc without requiring any patching. -fpermissive does most of the work of
allowing any conversion, I only had to add some code so "&operator new[]"
(overloaded) knew which conversion to pick.
Obviously the patch needs completing (I am certainly missing many things),
cleaning up, and additional work to allow conversions without -fpermissive, and
only those that differ only by extern "C" somewhere. In other words it still
needs to be (re)written ;-)
But I think it is very encouraging that it compiles gcc (including libstdc++)
without any patching (but lots of warnings), which means this bug might be
fixed without breaking too much user code (we can be more lax than sunpro,
which rejects gcc sources in 2 places). And I don't think it introduces too
much ambiguity (overloading on linkage still works on a few tests).
