Thanks for testing this. I have installed the following additional
patch, which I hope fixes your problem. It also fixes the misspelling
noted by Paolo Bonzini. Please give it a try when you have the time.
2007-02-28 Paul Eggert <[EMAIL PROTECTED]>
* lib/autoconf/c.m4 (AC_C_BIGENDIAN): Fix typo "__LITLE_ENDIAN__".
Problem reported by Paolo Bonzini in:
http://lists.gnu.org/archive/html/autoconf-patches/2007-02/msg00024.html
* tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
universal binaries. Problem reported by Elias Pipping.
