Hello,

This has to do with the default behavior configure in -make where we have:

if test "$ac_cv_library_combo" = ""; then
  case "$host_os" in
    darwin*)   ac_cv_library_combo=apple-apple-apple ;;
    nextstep4) ac_cv_library_combo=nx-nx-nx          ;;
    openstep4) ac_cv_library_combo=nx-nx-nx          ;;
    *)         ac_cv_library_combo=gnu-gnu-gnu       ;;
  esac
fi

So all non OS X Darwin platforms effectively have to be configured with 
--with-library-combo=gnu-gnu-gnu (once the gnu runtime is installed). 
All of this is explained in the reference the reference above.

BUT ...

... understand that once you've installed the gnu runtime (if you 
install it in the default location), you will may have issues with the 
apple runtime.  (i.e. when building apple runtime based ObjC code wrt 
which headers are found when you #include <objc/objc.h> and which 
library is linked when you use -lobjc.)

I'm working on a explanation for our Darwin documentation in response to 
a related thread.  But I may need some help from someone daring enough 
who actually has Darwin / OS X to verify/test some of it, once it's 
done, esp. wrt XCode.

Cheers,
David
