Hi,

After this patch series, I'm seeing build errors under Ubuntu Trusty
(targets x86_64 and arm-none-nacl, other arm and aarch64 unaffected)

There are loads of:
libtool: compile:  gcc -DHAVE_CONFIG_H -I. -I../../opcodes -I.
-I../../opcodes -I../bfd -I../../opcodes/../include
-I../../opcodes/../bfd -W -Wall -Wstrict-prototypes
-Wmissing-prototypes -Wshadow -Werror -g -O2 -MT dis-init.lo -MD -MP
-MF .deps/dis-init.Tpo -c ../../opcodes/dis-init.c -o dis-init.o
In file included from ../../opcodes/i386-opc.c:24:0:
../../opcodes/i386-tbl.h:30:9: error: missing initializer for field
'cpu64' of 'struct <anonymous>' [-Werror=missing-field-initializers]
         0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0 } },
         ^
In file included from ../../opcodes/i386-opc.c:23:0:
../../opcodes/i386-opc.h:358:20: note: 'cpu64' declared here
       unsigned int cpu64:1;
                    ^

Can you check/fix?

Thanks

Christophe
