I have no problems if it's not named AC_INTERIX. I only thought it 
would be the way to go, i.e. AC_USE_SYSTEM_EXTENSIONS was only a 
collection of individual macro calls. Please add the test whereever 
you like. I'm not that familiar with writing m4 scripts and not with 
autoconf's internals either. I just copied AC_AIX.
