:) The fix:

With this fix and Joerg's output.h hack, I got gcc to compile. Now I'm
getting a bunch of these errors from the linker:


avr-gcc -Wall -mmcu=atmega128 -g -O2 -Wl,-Map,osavr.map -o osavr  bitmap.o
dummy.o init.o int48.o main.o proc.o ptab.o sched.o srb.o syscalls.o
sysclock.o xmalloc.o
dummy.o: In function `dummy_start':
/home/roth/dev/osavr.old/build/src/../../src/dummy.c:81: relocation
truncated to fit: R_AVR_7_PCREL no symbol
dummy.o: In function `foo_start':
/home/roth/dev/osavr.old/build/src/../../src/dummy.c:134: relocation
truncated to fit: R_AVR_7_PCREL no symbol


Compiling the same project with my build of gcc/binutils from 2002-09-03
works fine, but today's cvs (both gcc and binutils) has the problem.
