The program source is trivial (yes, I've attached the .ii file as well):
   #include <avr/pgmspace.h>
   prog_uchar foo [10][10] = { 0 };
When compiled with g++ 4.3.0, this does not actually put the data in program
space.

      0       0     100     100      64 pgmspace43c++.o 

It works correctly with gcc 4.3.0 (from the same distribution), and it works
correctly with g++ 4.1
