While you *can* do that, it's not to be recommended.
When you use gnustep-make, the compiler arguments will all be supplied 
correctly for you.
If you want to see exactly what gnustep-make does, you can use 'messages=yes' 
argument to get it to print out the command line.
The other thing you can do is use gnustep-config to tell you what is needed ... 
but you really ought to use gnustep-make.
