Thanks ... OK, so we need to add the -Wno-deprecated everywhere in  
apple-gnu-gnu (and presumably, if you're compiling the gnustep-base  
Additions, also on apple-apple-apple).

The right fix still seems to be to update the Apple runtime code in  
gnustep-base to work with the new runtime if available, but in the  
meanwhile
if we add the -Wno-deprecated flag, we should probably add it inside  
gnustep-base so that when support for the new runtime is available, we
can remove it in sync. :-)

So I think that the right approach is:

 * have core/base/configure.ac detect that we're using the "new"  
Apple runtime [this test will be good in the future as well for when  
we actually
    add support for the new runtime ;-)]

 * in that case, have core/base/configure.ac add -Wno-deprecated to  
some autoconf output variable (eg, let's call it  
WNO_DEPRECATED_OBJCFLAGS),
    else leave it empty

 * have base.make.in set AUXILIARY_OBJFLAGS +=  
@WNO_DEPRECATED_OBJCFLAGS@ when running with the Apple runtime

Does that make any sense to you ?

Thanks for your help
