unknown type name 'huo_ast' compilation error

Trying to compile with gcc or clang on Debian jessie. Receiving the following error (and a similar error with clang). Seeing this on git commit 152af3b.

From what I can see this is the result of this ordering, because value.h makes use of the huo_ast type:

#include "value.h"
typedef struct huo_ast_t huo_ast;

I tried swapping the two lines and it worked.

typedef struct huo_ast_t huo_ast;
#include "value.h"

This issue can be closed if #59 is merged to master.

Thanks @snordgren for getting me over this hurdle
