Miscellaneous Bug

I think this is a bug. I'm not reporting it carefully because I doubt
anything will be done with it. It looks deep.

In <malloc.h>, we have a "struct mallinfo { ... };" and then also
a function "mallinfo()". Later in my code, a call to mallinfo is
munged from "mallinfo()" to "(mallinfo)". Presumably Sage++ doesn't
get the separation of the namespaces. (Are the separate? Guess so.)
