Ok, so you have a group of external headers that do evil things like
#define uint64_t. Here's what I do in cases like this.

//evil_prefix.h:
// Note: this file intentionally has no include guards.
#include "evil/a.h" // #defines uint64_t
#if !defined(uint64_t)
// these are the 3 offending lines copied from "evli/a.h":
#if defined(OS_WIN) && !defined(uint64_t)
#define uint64_t unsigned __int64
#endif
#endif // uint64_t

//evli_suffix.h:
// Note: this file intentionally has no include guards.
#undef uint64_t

Armed with the above two header files, in all your files _always_ include
all evil headers between the prefix and suffix includes:

#include "evil_prefix.h"
#include "evil/a.h"
#include "evil/b.h"
...
#include "evil_suffix.h"

If you follow the above rule, you can then include your files anywhere in
any order, and nothing should explode any more.
