i don't have it and i don't want to install it. I would like to check the 
Mac OS X header only if an Objective C compiler is present, as i have to 
use an objective c compiler (hance the AC_LANG_PUSH in the code). But it 
seems that the use of m4_ifdef is not sufficient.

do you have an idea of how to do that ?
