that's probably true, but I think it would be nice to be able to assume that if longptr points to a location containing 1L, then * (short int *) longptr == 1.
This doesnt work on sparc etc. Again mostly binary compatibility issues are there between programs which took pointers to fields which later got extended. All of them _have_ to be recompiled. On little endian, you can get away with not doing so.
