Including stdarg.h in 5eb9989 - why?

[Rostislav Svoboda]

Hi, in 5eb9989 Alan just included stdarg.h (see below) with comment:
    * lib-src/make-docfile.c: Include stdarg.h.

Can anybody explain me why? To me such a one-liner makes no sense.
I'm just curious what's the idea behind such a commit...

Thanx Bost

It's needed because make-docfile.c now uses symbols like va_list and 
va_start that stdarg.h defines. Without the change, make-docfile.c won't 
compile on platforms like MS-Windows where stdarg.h is not already being 
included by other .h files that make-docfile.c includes. See the thread 
starting here:
