* aclocal/enable-itron.m4: Remove changequotes (autoconf-2.49b). * aclocal/enable-posix.m4: Remove changequotes (autoconf-2.49b), use $host instead of $target (BUG-FIX). * configure.in: Use $target and $host instead of $target_alias and $host_alias (autoconf-2.49b). * aclocal/check-newlib.m4: Remove CC_FOR_TARGET (BUG-FIX) * aclocal/sysv-ipc.m4: Move AC_DEFINE outside of AC_CACHE (BUG-FIX) NOTES: * autoconf-2.49b depredicates using changequotes. * The changes to configure.in are due to cleanups in autoconf-2.49b's implemention of canonicalization. With autoconf-2.1x it wasn't always clear, when to use $xxx or $xxx_alias. Now this is clear.
