Question on -Werror usage in Makefiles...

[Andreas Jaeger <aj at suse dot de>]

Compiling current CVS I noticed these two warnings:

./xgcc -B./ -B/opt/gcc/3.4-devel/i686-suse-linux-gnu/bin/ -isystem /opt/gcc/3.4-devel/i686-suse-linux-gnu/include -isystem /opt/gcc/3.4-devel/i686-suse-linux-gnu/sys-include -L/builds/gcc/misc/gcc/../ld -O2  -DIN_GCC    -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -isystem ./include  -fPIC -g -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED  -I. -I. -I/cvs/gcc/gcc -I/cvs/gcc/gcc/. -I/cvs/gcc/gcc/../include  -fexceptions -c /cvs/gcc/gcc/unwind-dw2.c -o libgcc/./unwind-dw2.o
/cvs/gcc/gcc/unwind-dw2.c: In function `_Unwind_GetGR':

/cvs/gcc/gcc/unwind-dw2.c:189: warning: comparison between signed and unsigned
/cvs/gcc/gcc/unwind-dw2.c: In function `_Unwind_SetGR':

/cvs/gcc/gcc/unwind-dw2.c:227: warning: comparison between signed and unsigned

Looking at the commandline, I wonder why we do not pass -Werror to
this?  

I'll send a patch for the actual warning later but would welcome if
somebody fixes the Makefiles to actually use -Werror here.  Or is this
on purpose?
