As I repeatedly said before (This really is an FAQ):
You need to use an rtems-patched automake or automake >= 1.10 to be run
on the rtems sources - Vanilla automake-1.9 is NOT sufficient.
[Background: We need a patch applied to automake, which had been
incorporated into automake's CVS for more than 2 years, but there had
not been a release since then!
automake-1.10 finally has this patch integrated.]

Not quite. The AM_INIT_AUTOMAKE line above means this configuration
needs at least automake-1.9. It doesn't mean this configure script needs
In later versions of RTEMS (rtems-cvs), this had been changed to 1.10,
so you will need automake-1.10.
We could not change this earlier, because the snapshot you are using
predates automake-1.10, and had required you to use a patched version of
You apparently missed this and were using vanilla automake-1.9 instead.
