[hsteinhaus at gmx dot de]

------- Comment #2 from hsteinhaus at gmx dot de  2008-03-07 20:59 -------
version 4.2.1 seems to be affected as well:

--------------------------------------------
holger@x:~/scratch$ cat foo.cpp
#include <avr/pgmspace.h>

const int foobar1 = 42;
int foobar2 = 42;
const int PROGMEM foobar3 = 42;
int PROGMEM foobar4 = 42;

holger@x:~/scratch$ avr-g++ -Wall -mmcu=atmega1281 -c foo.cpp
foo.cpp:5: warning: only initialized variables can be placed into program
memory area
foo.cpp:6: warning: only initialized variables can be placed into program
memory area
holger@x:~/scratch$ avr-g++ --version
avr-g++ (GCC) 4.2.1 (SUSE Linux)
