I guess we need a better error message.

There are two separate exception handling mechanisms available ... one based on 
the standard setjmp() function (which does not require special compiler 
support), and one 'native' version where the compiler manages the exception 
handling.  If you try to use both in the same executable, exception handlers 
won't work... which can be pretty disastrous.

This warning is telling you that the gnustep-base library was built using one 
form of exception handling, but that the gnustep-make package you are using is 
building code to use the other form of exception handling ... with the 
consequence that exception handling would be broken in the program you are 
building.

So ... somehow your gnustep-base and gnustep-make package are incompatible, and 
you need to replace one of them with a version configured to match the other.
