Comment (by pmav99):

 OK, the problem seems to be that the generated gis.py (i.e.
 {{{lib/python/ctypes/OBJ.x86_64-pc-linux-gnu/gis.py]}}}), doesn't define
 {{{errcheck}}} for some of the functions, including {{{G_get_window}}} and
 {{{G_get_element_window}}}. Can anyone provide a hint, why these functions
 don't have {{{errcheck}}} defined while others do?
