#5012 fix fltk13-aqua_1.3.3-3 on Xcode 9

[Jack Howarth]

Currently the build of fltk13-aqua_1.3.3-3 on Xcode 9 fails with the compiler error...

Fl_Tree_Item.cxx:552:38: error: ordered comparison between pointer and zero ('Fl_Tree_Item *' and 'int')
    if ( from_parent->deparent(from) < 0 )      // deparent self from current parent
         ~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^ ~
1 error generated.

This can be worked around with the following Info file change modelled on the upstream inkscape patches reecently added to fink.
