Fortunately that file wasn't made dependent upon haproxy since it was integrated, better isolate it before it's too late. Its dependency on api.h was the result of the change from config.h, which in turn wasn't correct. It was changed back to stddef.h for size_t and sys/types.h for ssize_t. The recently added reference to MAX() was changed as it was placed only to avoid a zero length in the non-free-standing version and was causing a build warning in the hpack encoder.
