Ehm...
I'm sorry, but this code:

#define map_adjust_x(X)            \
  ((X) < 0                         \
   ? ((X) % map.xsize + map.xsize) \
   : ((X) >= map.xsize             \
      ? (X) % map.xsize            \
      : (X)))

will reopen the bug <http://www.freeciv.org/cgi-bin/bugs?findid=749>.

If we want to try to speed up Freeciv, we should also try to evaluate the 
impact of options like "-march=i686" or "-march=athlon" to gcc (all the 
recent x86 processors have CMOVs instructions that can eliminate many 
branches).
