Ok, I think you are right. But where do I have to change in null_val.c?
I gues snot only these lines have to be changed:
int G_is_null_value (const void *rast, RASTER_MAP_TYPE data_type)
int G_is_c_null_value (const CELL *cellVal)
int G_is_f_null_value (const FCELL *fcellVal)
int G_is_d_null_value (const DCELL *dcellVal)

The "const" is missing in "null-val.c". Can I simply replace e.g. all
"CELL" by "const CELL" etc.?
