[PATCH] replaced stdndup() with the inlined equivalent

[Lubomir I. Ivanov]

From: "Lubomir I. Ivanov" <neolit123 at gmail.com>

don't kill the OS incompatibility messenger.

1)
http://stackoverflow.com/questions/6062822/whats-wrong-with-strndup
stdndup() is POSIX 2008, but apparently not available on OSX and Windows
it could be made potentially application global (e.g. a local "stdndup.h")

2)
free() memory at pointer "current_dir", once we are done.
