I see. Seems it was a GNU extension but got standardized.
Would this do? According to vc6's stdarg.h va_list is just a struct 
containing the stack pointer and an offset. ECL seems to build fine and 
work if I include it.


#if defined(_MSC_VER) || !defined(va_copy)
#define va_copy(dst, src) \
    ((void) memcpy(&(dst), &(src), sizeof(va_list)))
