On systems where the assembler can handle quoted names, you can use this
macro to provide more human-readable names.
+@findex ASM_DECLARE_CLASS_REFERENCE
+@item ASM_DECLARE_CLASS_REFERENCE (@var{stream}, @var{name})
+A C statement (sans semicolon) to output to the stdio stream
+@var{stream} commands to declare that the label @var{name} is an
+Objective-C class reference. This is only needed for targets whose
+linkers have special support for NeXT-style runtimes.
