E.g. if you +are building a uclibc system, you certainly do not want glibc headers or OSX libc +headers to be picked up. To avoid that this patch is penetalizing certain common +Linux/Unix host directories. + +To send the patch upstream the evil paths should be specified by +a setting or command-line options. Until now this is a evil hack assuming +certain host system paths.
