glibc/stdio-common/tst-fmemopen2.c
Ulrich Drepper 1475e2012f * stdlib/tst-strtod2.c (do_test): Use %tu in fmt string for ptrdiff_t
value.

	* stdio-common/tst-fmemopen2.c (do_test): Avoid fmt string warning
	if off_t is different rank from size_t.

	* sysdeps/generic/unwind-dw2.c (extract_cie_info, execute_cfa_program,
	uw_frame_state_for): Avoid type punning warnings.
	* sysdeps/generic/unwind-dw2-fde-glibc.c
	(_Unwind_IteratePhdrCallback): Likewise.
	* sysdeps/generic/unwind-dw2-fde.c (_Unwind_Find_FDE): Likewise.
	(binary_search_single_encoding_fdes, binary_search_mixed_encoding_fdes,
	get_cie_encoding, linear_search_fdes): Don't mix char and unsigned char
	pointers.
