- Subject: [patch 4.0/4.1] sed command garbled when generating macro_list
I committed the second variant of this patch by accident in r112647 on
the trunk, now approved by Mark. Ok to apply to the 4.0 and 4.1
branches as well? Which variant?

* Makefile.in (s-macro_list): Don't put a backslash-newline in
a random spot in a sed script; this has undefined behavior according
to POSIX, and Solaris 8 sed rejects it.
