15.12:  How can I write a function which takes a variable number of
        arguments and passes them to some other function (which takes a
        variable number of arguments)?
Bah .... I consulted that very same FAQ a coupla days ago. I checked Q's 
15.4, 15.5 and 15.7, but didn't notice 15.12 :-)
A:      In general, you cannot.  Ideally, you should provide a version
        of that other function which accepts a va_list pointer
        (analogous to vfprintf(); see question 15.5 above).  If the
        arguments must be passed directly as actual arguments, or if you
        do not have the option of rewriting the second function to
        accept a va_list
Well, of course, 'vprintf' (and 'gmp_vprintf') both accept a va_list - 
so they don't even need to be rewritten. I think this *is* an option 
.... now, if I can just get my head around the finer points of what 
needs to be done ...

Thanks Eric.
