+
+       * configure: Add arm-wince, mips-pe and sh-pe targets.
+       * configure: Regenerate.
+
+       * config/obj-coff.h (COFF_WITH_PE): Define for mips-pe and
+       sh-pe targets.
+       (TARGET_FORMAT): Set to "pe-shl" for the sh-pe target and to
+       "pe-mips" for the mips-pe target.
+
+       * config/tc-arm.c (insns): Change displacement encoded in BL
+       and B instructions if the target port is arm-wince.
+       (do_ldst): Do not bias the relocation offset if the target
+       port is arm-wince.
+       (md_pcrel_from): Add in missing relocation offset bias if the
+       target os arm-wince.
+
+       * config/tc-mips.c (mips_target_format): Support COFF flavour.
+       (md_begin): Disable -G support for mips-pe target.
+       (md_apply_fix): Treat BFD_RELOC_RVA reloc as BFD_RELOC_32.
+       * config/tc-mips.h (USE_GLOBAL_POINTER_OPT): Add support for
+       COFF flavour.
+
+       * config/tc-sh.c (md_begin): sh-pe target is little endian.
+       * config/tc-sh.h (SUB_SEGMENT_ALIGN): If using a BFD
+       assembler, just set the alignment to 4.
+
+       * config/te-wince-pe.h: New file for WinCE targets.  Define
+       TE_WINCE.
