Some stupid idea just crossed my mind: what if the /ports version just 
re-arranges the va_list according to the positional args and calls 
vsnprintf()?
At least we know compiler and library...

Or, another idea: why not format the va_args individually using the original 
format specifiers alone (without positional args), and assemble the resulting 
string?

Am I on dope? Or does this sound at least doable?

Didn't code too much C lately...

 Jörg
