Macros: type declarations

[edsko]

It is important that we deal with macros that declares types, because we should (at least have the option to) reflect these types in the Haskell bindings. For example, given

#define	__S16_TYPE		short int

we should not replace __S16_TYPE with short int in the generated bindings, ideally.

This is also important in the generation of the prelude (this particular example comes from /usr/include/x86_64-linux-gnu/bits/types.h).

[edsko]

Self-assigning this right now because I am working on the parser for macros. Am not intending to also deal with binding generation just yet.

A problem is what does libclang say about

typedef __S16_TYPE somethingElse;

do we still see __S16_TYPE there. I doubt?

[edsko]

Perhaps not directly, but if not, we can probably recover the information.
