	* coff-arm.c (coff_thumb_pcrel_12, coff_thumb_pcrel_9,
	insert_thumb_branch, record_thumb_to_arm_glue): Suppress
	definition of these functions for ARM_WINCE builds as they are
	not used.
        (SWAP_IN_RELOC_OFFSET, SWAP_OUT_RELOC_OFFSET): Do not define
	for ARM_WINCE builds.

	* config/tc-arm.c (thumb_add_sub): Do not convert a subtract of
	zero into an add of zero - it is not the same.

	* emultempl/armelf.em (PARSE_AND_LIST_SHORTOPTS): Add 'n' in order

	"--no-pipeline-knowledge".
