[Freeciv-Dev] (PR#12539) patch for GCC 4

["Vladimir Kondratiev" <vladimir.kondratiev@xxxxxxxxx>]

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=12539 >

Attached is patch to compile 2.0 beta8 (with GCC 4, I have no 3.x
versions handy to check).
GCC 4 don't like definition of array of unknown structures.
