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

 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?
