[Build-failure] elf32-score.c compilation warning





Hi Pierre, 
     there are some 48-bits instructions in the new score target.  so ,It 
must add "--enable-64-bit-bfd " to the configure command if your gdb's 
version is 6.8. The last gdb and binutils already added the option to 
configure file. please checkout the lastly version from binutils.org.

Cheers

 Building gdb with
 --enable-targets=all
but without --enable-64-bit-bfd.
on cygwin (windows 32 bits).
I get a bfd compilation error,
that does not appear with
--enable-64-bit-bfd.

I think that there is a configuration problem
for elf32-score:


libtool: compile:  gcc -DHAVE_CONFIG_H -I. -I../../purecvs/bfd -I. -I.
-I../../p
urecvs/bfd -I../../purecvs/bfd/../include -W -Wall -Wstrict-prototypes
-Wmissing
-prototypes -Werror -g -O2 -c ../../purecvs/bfd/elf32-score.c -o
elf32-score.o
../../purecvs/bfd/elf32-score.c: In function `score3_bfd_putl48':
../../purecvs/bfd/elf32-score.c:290: warning: right shift count >= width 
of
type

There other errors are at the end of the email.
The corresponding lines do shifts of 32 or 48 bits,
which is indeed too large for 32 bit addresses,
so these addresses are probably 64 bit, no?
