I'm not sure whether CMake solves the issue: how to generate
single config.h supporting multiple architechtures, because
CheckTypeSizeC.c.in of CMake-2.6.0:

#define SIZE (sizeof(@CHECK_TYPE_SIZE_TYPE@))
const char info_sizeof[] =  {'I', 'N', 'F', 'O', ':', 
's','i','z','e','o','f','[',
  ('0' + ((SIZE / 10000)%10)),
  ('0' + ((SIZE / 1000)%10)),
  ('0' + ((SIZE / 100)%10)),
  ('0' + ((SIZE / 10)%10)),
  ('0' +  (SIZE    % 10)), 
  ']','\0'};


#ifdef __CLASSIC_C__
int main(){
  int ac;
  char*av[];
#else
int main(int ac, char*av[]){
#endif
  return (&info_sizeof[0] != &info_sizeof[0]);
}

It looks like as if it's compiled and executed on native
system (and it won't check the size in cross building).
Could you write small demonstration to check the sizes
of int and long by CMake, for cross-building case?
