[PATCH] COPYING and copying.c

[Eli Zaretskii]

The following is one of the gotchas with case-insensitive file names.
It got me puzzled for about 10 seconds when I saw Make trying to
compile COPYING.c into COPYING...

(It turns out Robert Hoehne already bumped into this while working on
GDB 4.18, but he ``handled'' it by commenting out the whole rule...
Ts, ts, ts ;-).

I hope this solution is acceptable.  If not, please tell me how to
change it.

	* Makefile.in (copying.c): Depend on copying.txt, not COPYING.
	(copying.txt): New target, a link to COPYING.
