commit 4fcdfbfcf9d5c5a313da43f78309aa2745b2dc32
Author: Rical Jasan <ricaljasan@pacific.net>

    manual: Update @standards for [__]va_copy.
    
    The ISO version in which va_copy was introduced is made explicit, and
    __va_copy is given @standards.  The description is updated to be more
    clear about the origins of each macro, and the reader is informed
    these macros are now provided by the compiler (information previously
    embedded in a Texinfo @comment).
    
    	* lang.texi (va_copy): Change standard from ISO to C99.
    	(__va_copy): Add standard and header annotation.
    	Update description for clarity of origins and current use.

 The @code{va_copy} macro allows copying of objects of type
 @code{va_list} even if this is not an integral type.  The argument pointer
 in @var{dest} is initialized to point to the same argument as the
 pointer in @var{src}.
