Please describe the problem:
The recent change in libgnome-2.8.2's gnome-program.c to initialize args to 0,
then pass it to gnome_program_init_common() breaks compilation on FreeBSD am64
and Alpha (at least).  I have a feeling the same will be true on RedHat Alpha.

Steps to reproduce:
1. Try to compile libgnome-2.8.2 or HEAD on FreeBSD amd64 or alpha.
2. 
3. 


Actual results:
The compilation aborts complaining argument 8 to gnome_program_init_common() is
not of the right type.

Expected results:
The compilation should succeed.

Does this happen every time?
Yes.

Other information:
The fix is to revert the initialize fix.  That is, if va_list args is left
uninitialized, the compilation succeeds on all tested architectures.  However,
the better solution is probably to pass the va_list argument as a pointer or do
some ifdef checking to properly set the argument for architecture on which
libgnome is being compiled.
