Added 'const' keyword to PSTR definition per Johann's recommendation in comment #1.

This is addressed in

http://gcc.gnu.org/PR44643

Besides changes in avr-gcc, definition of include/avr/pgmspace.h:PSTR has to be changed from

# define PSTR(s) (_extension_({static char __c[] PROGMEM = (s); &__c[0];}))

to

# define PSTR(s) (_extension_({static const char __c[] PROGMEM = (s); &__c[0];}))

with this change avr-libc should build (didn't try it, but there no reason for avr-gcc ICEing any more).

The changes in avr-gcc will lead to a more comprehensible error massage instead of a fatal abort. However, fixing PSTR will still be needed.

Example of the error:

avr-gcc -DHAVE_CONFIG_H -I. -I../../../../avr/lib/avr2 -I../../.. -I../../../../common -I../../../../include -I../../../include -g -Wall -W -Wstrict-prototypes -mmcu=avr2 -D__COMPILING_AVR_LIBC__ -mcall-prologues -Os -MT dtostre.o -MD -MP -MF .deps/dtostre.Tpo -c -o dtostre.o ../../../../libc/stdlib/dtostre.c
../../../../libc/stdlib/dtostre.c: In function ‘dtostre’:
../../../../libc/stdlib/dtostre.c:63:2: internal compiler error: in build_unary_op, at c-typeck.c:3786

So the build can't go on. As I seen, there's also on line 68 and inside other files like vfscanf etc.

Version of GCC: avr-gcc (GCC) 4.6.0.
