Thanks.  However, I think the FSF doesn't want us to use year ranges
(as in "1998--2000"), so I used explicit years instead.

This works for me with Bash.  Hmm.  Does it work if you replace
"$(REFEDITS)" with $$REFEDITS ?  (You might need to "export REFEDITS"
somewhere in the Makefile.)

There are no quotes around the refedits variable, that
is the problem. Yes, it seems that bash does not need
them in a for/in/do/done construct after "in" when the
variable passed is empty, unlike the original Bourne shell.
Looks like almost everybody compiling gdb docs must be
using bash; I was quite suprized some time ago to see
that a simple "make ps" did not work in the docs directory.
