Well, this is *extremely* odd.  I don't see it on i386-linux either, and it's
still there with Adreas patch applied in both stage1 and stage2 compilers:

stage2/xgcc -Bstage2/ -B/home/bernie/src/m68k-netbsdelf-HEAD-install/m68k-unknown-netbsdelf1.6.2./bin/ -c   -g -O2 -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic -Wno-long-long -Wold-style-definition -fno-common   -DHAVE_CONFIG_H    -I. -I. -I../../combined-HEAD/gcc -I../../combined-HEAD/gcc/. -I../../combined-HEAD/gcc/../include  ../../combined-HEAD/gcc/bb-reorder.c -o bb-reorder.o
../../combined-HEAD/gcc/bb-reorder.c: In function `reorder_basic_blocks':
../../combined-HEAD/gcc/bb-reorder.c:186: warning: 'count_threshold' might be used uninitialized in this function


Could you please try running this exact command line on your system to
make absolutely sure it's only happening on m68k-netbsdelf?

I'm puzzled.
