the line has several m68k-netbsd strings in it. Here is what I see:
stage2/xgcc -Bstage2/ -B/usr/m68k-rz-linux/bin/ -c -g -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic -Wno-long-long -Wold-style-definition -Werror -DHAVE_CONFIG_H -I. -I. -I../../gcc-3.4-20040107/gcc -I../../gcc-3.4-20040107/gcc/. -I../../gcc-3.4-20040107/gcc/../include ../../gcc-3.4-20040107/gcc/bb-reorder.c -o bb-reorder.o
## no warnings
Anyway - is it at all reasonable to have -Werror quit on "might be used
uninitialized" warnings? It is really very dependent on gcc version and
possibly other circumstances so it makes -Werror probably less usefull
than it could be.
