If you compile the program as C++ rather than C, then these
errors go away, and GCC 4.3.1 propagates the constants to the
printf call:

        movl $6, 8(%esp)
        movl $7, 4(%esp)
        movl $.LC0, (%esp)
        call printf

This is one difference in the meaning of const between C and C++.
Another difference is that in C++, const variables defined
outside of functions are static by default, although one can
override that with extern.  That doesn't matter in your program
because the variables were static already.
