Suppose the GCC-supplied "stddef.h" were to do stuff like:

and the DJGPP headers were to do the same?  :-)

And because the main shell script version has been removed,
I pulled the support for doing c-fixes from a command line.
But I thought you-all used "fixinc.winnt" anyway?  Since I
don't have a Windows dev box, I was never planning on touching
that mechanism.  However, I would work with anyone among the
djgpp-workers interested in making the fixincl program run
under Win*.  :-)
