* varasm.c (output_constant_def_contents): Use
ASM_DECLARE_CONSTANT_NAME if defined.
* doc/tm.texi (Label Output): Document ASM_DECLARE_CONSTANT_NAME.
* config/darwin.h (ASM_DECLARE_OBJECT_NAME): Ensure zero-sized
objects get at least one byte to prevent assembler problems.
(ASM_DECLARE_CONSTANT_NAME): New.
Index: testsuite/ChangeLog
* gcc.c-torture/compile/zero-strct-2.c: New test.
