Thanks for the quick response. Ok, the point is always use autoconf
from the original source code, not use the autoconf coming with the
platform.

BTW, in my understanding, patch posters do not need to submit a patch
for configure, a patch for configure.ac is enough since configure will
be generated by committers anyway (if the patch gets committed).

Best reagards,
