MFC: Add memrchr(3).
I think this is not very good idea to MFC that into stable releases 6.x
and 7.x. The reason is that configure scripts for some packages might
detect up this API and enable it. Which means that some binary-only
packages build for say 6.4 won't work on 6.3 and down. AFAIK, both
forward and backward compatibility is required (or at least desired?)
for stable branches.
No, it isn't. Backwards compatibility (in the sense that stuff that worked
on 6.x should still work on 6.x+1) is largely required unless there is
some very good reason to break compatibility (such very good reasons are
quite rare.)
Which reasons are they specifically? I can't think of any. The memrchr()
is not something mandated by the C90 and/or POSIX/SUS. Any software that
is portable should be able to live without it.
