Build Bug Fix! Probably. Back up your shit if you've not been getting that bug

Browse source 
Noticed something seemed to be acting up with scan_includes when checking if the bug was present on cygwin, which it was for me, so I went to check to see if there was an update to it for vanilla pokecrystal and YEP

- Updated scan_includes.c to the current version present in pokecrystal, seems to fix bugs preventing some people from building.
