+* Add new option --use-nul-prefixed-import-tables to dlltool to allow fall-
+ back to old import table generation with null element prefix.
+
* Support for PowerPC booke64 instructions has been removed. The assembler no
longer accepts -mbooke32 or -mbooke64 and the disassembler no longer accepts
-Mbooke32 or -Mbooke64. Instead, -mbooke and -Mbooke should be used.
