How to add Objective-C to GCC

I'm installing gnustep on a system where i have GCC 4.1.2 without
objective-c support.

i had added sucessfully gnustep-make, gnuste-base generates lots of
GNUstepmakefiles
and even, when i tried to build Gworkspace, it had configure properly
without asking for gnustep-gui.

But when i send "make install" i have the "objective-c compiler no
installed".

I tried to bootstrap again GCC 4.1.2 and nothing. This is a system
called Syllable 0.6.6 wich i'm actually tweaking..
