Hi,

 In the C++ front end, default arguments are recorded in
FUNCTION_TYPEs intead of being part of the FUNCTION_DECLs.  What are
the reasons for that?

There used to be an extension that allowed default arguments on function
pointer types.  We agreed to kill it, although I don't know if it was
actually removed.  If that's been done, there's no longer any reason.

I took it out the back and shot it.

The obvious place is on the DECL_INITIAL of the PARM_DECLs, but I don't think they exist until the function is defined.
