[Bug c++/38342] New: __attribute__((__progmem__)) not propagated from typedef to data

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.

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

------- Comment #4 from j at uriah dot heep dot sax dot de  2008-12-01 10:37 -------
Note that this is a GCC 4.3.x regression; GCC 4.2.x compiled the code the
way expected.
