A few days ago, I sent out a query regarding AT&T C++ 2.1 and stdargs.
Apparently, there is a bug in cfront which caused the problem.  The
following message from a guy at AT&T explains how to fix it (he may
well have posted it to the news as well - sorry about any
duplication):

There's a bug in "src/print2.c" around line 1490--

		if (body && Cast==0) {

				putstring(", va_alist");
#endif
			putch(')');
		}
		else
			putch(')');
