Re: Get rid of lvalue casts etc.


I've committed now the appended version of the patch,

Andreas

2004-02-07  Andreas Jaeger  <aj@suse.de>

	* iconv/gconv_simple.c (ucs4le_internal_loop): Remove cast used as
	lvalue.
	(internal_ucs4le_loop_single): Likewise.
	(ucs4_internal_loop): Likewise.
	(BODY): Likewise.
	(internal_ucs4_loop_single): Likewise.
	* iconvdata/iso8859-1.c (BODY): Likewise.
	* iconvdata/cp1255.c (EMIT_SHIFT_TO_INIT): Likewise.
	* iconvdata/cp1258.c (EMIT_SHIFT_TO_INIT): Likewise.
	* iconvdata/gb18030.c (BODY): Likewise.
	* iconvdata/armscii-8.c (BODY): Likewise.
	* stdlib/msort.c (msort_with_tmp): Likewise.
	
	* iconv/gconv_open.c (__gconv_open): Remove conditional expression
	as lvalue.
