I just spent several minutes on IRC with Roman debugging another failure
of the new gettext autom4te tracing on BSD systems.  It turns out that
on BSD, 'autom4te' is a wrapper script:

http://svnweb.freebsd.org/ports/head/devel/autoconf-wrapper/files/autotools-wrapper.sh?revision=300896&view=markup

but the wrapper script foolishly executes:

stuff | { more stuff; exec /bin/autom4te-2.69 "$@" }

which means any use of "echo blah | autom4te -" fails because stdin was
eaten before executing the real autom4te.  Yet another limitation of
tracing that gettext needs to workaround in its attempt to use m4
tracing rather than sed scripts.  You'll have to use an actual file name
instead of - for stdin, since we cannot guarantee that everyone will
have a working autom4te in their path that doesn't eat stdin.
