C wants to know the size of things when allocates space for variables. One
way around that is to use pointers, because the compiler knows the size of
pointers. You can use a (void*) pointer as your variable and then cast it
to a pointer of whatever struct you want.

# struct {
#
# int : 0;
# long : 5;
# short : 2;
# } s;

It's about using integers smaller than their natural size packed into a
structure.

You hate people.
But I love gatherings. Isn't it ironic.
