   Building the gdb 7.9 release on x86_64-apple-darwin14 produces many
warnings of the form...

remote.c:2567:1: warning: unused function
'VEC_thread_item_t_embedded_size' [-Wunused-function]
DEF_VEC_O(thread_item_t);
^
./common/vec.h:435:20: note: expanded from macro 'DEF_VEC_O'
VEC_T(T);                                                                 \
                                                                          ^
./common/vec.h:863:22: note: expanded from macro '\
DEF_VEC_FUNC_O'
static inline size_t VEC_OP (T,embedded_size)                             \
                     ^
./common/vec.h:399:22: note: expanded from macro 'VEC_OP'
#define VEC_OP(T,OP) VEC_##T##_##OP
                     ^
<scratch space>:55:1: note: expanded from here
VEC_thread_item_t_embedded_size
^

Shouldn't those VEC declarations use a wrapper to avoid them on
targets not supporting that code?
