What needs to be updated?
If the priv member isn't renamed, the code must only be
recompiled. If the direct accessable members are put at the
beginning of the struct and arent't changed, even recompilation
isn't necessary.

If a stable ABI is desired, you'll need access functions
for everything (macros arent't enough).
In this case, I would recommend to make the struct completely
anonymous (put only a forward declaration in the .h file and
the struct definition into the .c file). In this case, gcc will
not allow to access any struct members directly from another
.c file.
