Update.
* iconv/skeleton.c: Define access macros with u suffix. Adjust #if expression for use of unaligned function to the one used in the definition of these functions. * iconv/gconv_simple.c (internal_ucs4_loop_unaligned): New function. (internal_ucs4le_loop_unaligned): New function. Ralf Baechle <ralf@uni-koblenz.de>
