I didn't notice before sending in my last report, but the assert.h
that was being used was from a previous gcc release.  (The directory I
was in had only my gcc object files, not sources and header files.)
Here's the header file I was really using:

   /* Allow this file to be included multiple times
      with different settings of NDEBUG.  */
   #undef assert
   #undef __assert

   #ifdef NDEBUG
   #define assert(ignore)
   #else

   #define assert(expression)  \
     ((expression) ? 0 : __assert (#expression, __FILE__, __LINE__))

   void __eprintf ();		/* Defined in gnulib */

   #ifdef __GNUC__
   volatile void abort();
   #else
   void abort();
   #endif

   #ifdef __STDC__

   #define __assert(expression, file, line)  \
     (__eprintf ("Failed assertion " expression		\
		 " at line %d of `" file "'.\n", line),	\
      abort ())

   #else /* no __STDC__; i.e. -traditional.  */

   #define __assert(expression, file, line)  \
     (__eprintf ("Failed assertion at line %d of `%s'.\n", line, file),	\
      abort ())

   #endif /* no __STDC__; i.e. -traditional.  */

   #endif

This doesn't change the fact that the expansion seems incorrect.

Also, some line breaks appear to have been added by my local mailer;
the big ugly expression really was all one line.
