Ok, avr-libc-20020203 with c++ patch builds fine (with the missing files 
added to the patch).  When I try to compile some previously good code which 
was fine with gcc-3.0.3 (without m128 and c++ patches) I have a 
problem.  See below

avr-gcc -mmcu=at90s2313 -Wall -W -Wstrict-prototypes  -Os -mtiny-stack 
-mcall-prologues -mrtl -g   -c -o pavr.o pavr.c
avr-gcc pavr.o -o a.out -mmcu=at90s2313 -Wl,-M > a.map
/usr/local/lib/gcc-lib/avr/3.0.4/../../../../avr/lib/crts2313.o: In 
function `__c_startup__':
../../libc/gcrt1.S:161: undefined reference to `_data_load_start'
../../libc/gcrt1.S:162: undefined reference to `_data_load_start'
../../libc/gcrt1.S:179: undefined reference to `_data_end'
make: *** [a.out] Error 1


You can try this yourself, just run make in uisp-20011025/pavr and let me 
know if you see the same result.

Cheers,

Jason
