/* Why do this? Well PATH_MAX may vary from when eina itself is compiled
* to when the app using eina is compiled. exposing the path buffer below
* cant safely and portably vary based on how/when you compile. it should
* always be the same for both eina inside AND for apps outside that use eina
* so define this to 8192 - most PATH_MAX values are like 4096 or 1024 (with
* windows i think being 260), so 8192 should cover almost all cases. there
* is a possibility that PATH_MAX could be more than 8192. if anyone spots
* a path_max that is bigger - let us know, but, for now we will assume
* it never happens */
