The macro map_adjust_x() returns map.xsize when called with x==k*map.xsize 
and k is negative.
Eg: map_adjust_x(-map.xsize) will return map.xsize.

Patch for common/map.h attached (the redundant modulus calculation is 
eliminated when running gcc with the -O2 option).

Note that normalize_map_pos() in common/map.c is already correct.

ciao
