Something is going wrong here - it was supposed to be compiling test.m here,
not test.c ;-)

I suggest when you try to switch to Objective-C, create a new empty directory, 
and put only test.m and your GNUmakefile in there.  Make sure to do all changes 
to the GNUmakefile, then try again.

Let me know if that works :-)

Thanks
