Bug: HAVE_VPRINTF missing from autoconf

Hello,

Compiling omniORB4 CVS snapshot with gcc 3.3 CVS snapshot, I ran into 
a problem where the compilation failed with the messages:

#error "GCC no longer implements <varargs.h>."
#error "Revise your code to use <stdarg.h>."

This comes from cccp.c in omniidl, and is caused by the fact that the 
guarding HAVE_VPRINTF is never defined.

I think something like the following patches should fix this

Unfortunately I don't seem to have recent enough autoconf at hand to 
test this.
