Is this actually what gcc does?  The documentation I've seen suggested that gcc tries to apply a function type attribute in the decl spec to the return type if it's a function pointer, and otherwise tries to apply it to the function itself.  But maybe I'm misinterpreting it, or maybe that documentation is incorrect:
  http://developer.apple.com/mac/library/DOCUMENTATION/DeveloperTools/gcc-4.0.1/gcc/Attribute-Syntax.html#Attribute-Syntax

At any rate, please do more investigation.  If this is the right thing to do, we'll do it, but until we have a clear idea what on earth gcc is doing here, I'd rather hold off.

John.
