You will also need to de-reference the pointer using special
functions/macros, not just *p. Check out the avr-libc
man page on program space string utilities:

        http://www.nongnu.org/avr-libc/user-manual/group__avr__pgmspace.html

I think you need to use similar access methods with the IAR
tools, but I am sure there will be small differences that
can cause problems.
