	PR binutils/17512
	* dwarf.c (eh_addr_size): Use an unsigned type.
	(size_of_encoded_value): Return an unsigned type.
	(read_leb128): Break if the shift becomes too big.
	(process_extended_line_op): Do not read the address if the length
	is too long.
	(read_cie): Warn and fail if the pointer size or segment size are
	too big.
	* dwarf.h (DWARF2_External_LineInfo): Delete unused and incorrect
	structure definition.
	(DWARF2_External_PubNames): Likewise.
	(DWARF2_External_CompUnit): Likewise.
	(DWARF2_External_ARange): Likewise.
	(DWARF2_Internal_LineInfo): Use dwarf_vma type for
	li_prologue_length.
	(eh_addr_size): Update prototype.

	* coffcode.h (styp_to_sec_flags): Use an unsigned long type to
	hold the flag bits.
	* peXXigen.c (pe_print_reloc): Use unsigned types to hold the
	size and number of relocs.
	(pe_print_debugdata): Use a 32-bit aligned buffer to store the
	codeview record.
	* versados.c (process_otr): Check the esdid value before using it
	to access the EDATA.
