I agree, I just wanted to make sure you weren't opposed to using 
default_conversion in C as well and were ok with my explanation of why I 
was testing FUNCTION_DECL for some attributes (in C++, default_conversion 
will accept anything, so I am doing that for the sake of C).

An alternative could be to have a helper function that does nothing in C 
and calls default_conversion in C++. Or make the C version of 
default_conversion return its argument unchanged instead of asserting when 
it sees an unexpected tree.

I'll wait for Jason, thanks.
