Distribution/Version: Ubuntu (Hoary), AMD64

[ CC'ing Kjartan, since it seems he broke it :) ]

The change to libgnome/gnome-program.c in revision 1.73 broke the build on
AMD64.  The error is as follows:
  gnome-program.c: In function `gnome_program_init_paramv':
  gnome-program.c:1931: error: invalid initializer

The relevant change can be seen here:
  http://cvs.gnome.org/viewcvs/libgnome/libgnome/gnome-program.c?r1=1.72&r2=1.73

This initialiser will only work if the va_list type is an integer or pointer
type.  On AMD64 Linux, it appears to be an array type, so we get a compiler
error.  It probably affects some other platforms too.

Note that even though args was uninitialised, it doesn't get used by
gnome_program_init_common() if nparams != -1, so nothing bad happens.

To protect against using the unitialised variable, an assertion like the
following could be added to gnome_program_init_paramv():
  g_return_val_if_fail (nparams >= 0, NULL);

This should ensure that the problem is never occurs, but will probably still
leave the warning ...
