Generate bindings for macros #43
Comments

I'm going to do some work on this as part of parsing the standard library header files. |

The idea is to have some bootstrapping code as part of `hs-bindgen` that trawls the C standard headers looking for type definitions (such as `uint64_t`); these types should become part of a prelude, which we can recognize out of the box (so that instead of generating a new typedef for `uint64_t` every time we generate bindings, we use the one and only from the prelude). Since the standard headers also contain a whole bunch of macros, and we anyway want to support generating bindings for specific forms of macros (#43), this also has the beginnings of a parser for C macros.

This is a catch-all ticket currently for generating bindings for "all" macros, though we will almost certainly have to do this on an ad-hoc basis, supporting macros of a certain shape only:
