gcc 2.95.2, Tru64 4.0f: va_list declared twice by gcc headers

[Jonathan Lennox]

When I compile the program 'va-test.c' below on a Tru64 (OSF/1) 4.0f
system, I get the error messages that follow:

In file included from /usr/local/lib/gcc-lib/alphaev6-dec-osf4.0f/2.95.2/include/stdarg.h:36,
                 from va-test.c:2:
/usr/local/lib/gcc-lib/alphaev6-dec-osf4.0f/2.95.2/include/va-alpha.h:36:
warning: redefinition of `va_list'
/usr/local/lib/gcc-lib/alphaev6-dec-osf4.0f/2.95.2/include/va_list.h:7:
warning: `va_list' previously declared here

If the order in which <stdio.h> and <stdarg.h> are included is switched, the
error message goes away.

Both of the files which generate the error messages seem to be include files
distributed with gcc, not ones created by fixincludes.

Is there a patch for this?

Here's the full compile output:
