[En-Nut-Discussion] QT fails on dirtraverser.cpp

[Ulrich Prinz]

Hi!

Just tried to compile myself a recent version of qnutconf. But it fails
on dirtraverser.cpp as free() is not declared in this scope.

I simply added a #include <stdlib.h> and it works now.

But I use the open-source version of QT (mingw32 based) so there might
be a difference to the commercial version.

Just tell me if I should commit this fix or if there is more to be done
in that case.
