I'm not so sure now.
I've tested on a pretty wide range of systems
(did this: for i in $(type -a -p sed); do echo bc |$i 's/a\{0,1\}bc/x/';done)
and it worked fine (printed `x') for each version of sed on each of those
systems.
I tested on a few flavors of Suns (sunos4.1.4, 5.5.1, 5.6, 5.7),
HPUX 10.20, Linux, irix 6.2 & 6.5, NetBSD 1.3.1, AIX 2.4.
I saw the earlier thread (on the autoconf list) on this topic where
someone found that `?' and \| were not portable. Has anyone found a
system on which \{m,n\} is not portable?
