Absolutely.  Someday va_copy should be available everywhere... as with
all changes to C, it may be a while.  Actually, in GCC 3:

#if !defined(__STRICT_ANSI__) || __STDC_VERSION__ + 0 >= 199900L
#define va_copy(d,s)    __builtin_va_copy((d),(s))
#define __va_copy(d,s)  __builtin_va_copy((d),(s))

So C99 in non-ANSI mode has va_copy, and otherwise everyone has
