I did make autoreconf work but i had to change the autoconf version to 2.69 on:
override.m4:32 [m4_define([_GCC_AUTOCONF_VERSION], [2.69])])
They were both 2.64 and autoreconf complains about it.

It works now :)
>>> Also, I added the following to libstdc++v3's acinclude.m4:
>>> AC_DEFUN([GLIBCXX_ENABLE_NEW_OPNT_IF], [
>>> GLIBCXX_ENABLE(new-opnt-if,$1,,[enable if on new_opnt instead of while])
>>> if test $enable_new_opnt_if = yes; then
>>> AC_DEFINE(_GLIBCXX_NEW_OPNT_IF, 1,
>>> [Define is new_opnt will be used instead of while.])
>>> AC_MSG_CHECKING([for enabled if])
>> This message isn't very helpful.
Im working on the flag name and the messages, is there any rule for
this? or any personal suggestion?
