Arrgggh, indeed, sorry!

We should revert that patch, but then I’m not sure how to properly fix
the initial problem, which is that gen-scmconfig.c ends up using
Gnulib’s <stdio.h> etc.

Could Madsy check, after reverting the patch, if it works when doing
things in this order:

  /* Include the “real” headers.  */
  #include <stdio.h>
  #include <stdlib.h>

  /* Get the useful definitions.  */
  #include <config.h>

It has to be tested when compiling to a different OS, like MinGW as
Madsy did.
