Oh ... I see.  You are right - it's more complicated.

Your problem is that the first time you configure gnustep-make, the new libobjc 
is not
yet installed, but gnustep-make will try compiling the ObjC snippet to check if 
native
exceptions actually work.  That will fail, but then you can't compile the new 
libobjc! ;-)

Interesting chicken-and-egg problem.

Presumably we need a configure flag to force native-exceptions even if the 
compiler would
seem to fail when compiling them ?

Then you'd do

cd core/make
./configure --enable-native-exceptions-even-if-they-seem-not-to-work
make install
cd ../../dev-libs/libobjc
make
make install
cd ../../core/make
./configure --enable-native-exceptions
make install

Hmmm.

Thanks
