Bug squashed.  The problem was that output was closed with `close'
rather than `fclose', so buffered output never made it to the file.

With the patch below, the headers locale.h and stddef.h get fixed for
NULL (they define it unconditionally), and math.h gets fixed for the
exception thingy (which is not really required, since our math.h is
already protected against C++).  testing.h winds up identical to
itself, as it should, I think.

(The second patch below has nothing to do with the bug, it just gets
in my way when I'm trying to run the program outside the shell script
or under GDB, and forget to define $VERBOSE.)

	* fixinc/fixfixes.c (main): Close standard streams with fclose
	rather than close, to flush any buffered output.

	* fixinc/fixincl.c (initialize): Don't crash if $VERBOSE is
	undefined.
