But that couldn't possibly work.

The program is compiled.  It has compiled into it code which knows
that off_t is 4 bytes long.  E.g. it only allocates 4 byts on the
stack for off_t, that sort of thing.  It couldn't possibly work with
an 8 byte off_t.

Change the size of a data type, in a language like C, will always
force a recompile...
