Yes, I think gnustep-config still needs to go a bit further and add

GNUSTEP_CFLAGS
GNUSTEP_CPPFLAGS
GNUSTEP_LDFLAGS
and possibly some more stuff

as we still need to hard code the obsoleted 
-I$GNUSTEP_SYSTEM_ROOT/Library/Headers, etc
I assume this will happen when --includedir/--libdir/--bindir etc, etc 
are supported as per
the TODO in common.make:264

It definately seems the autoconf way to check system capabilities 
regardless of
platform, if one takes this stand AC_CHECK_NATIVELIBRARY seems out of 
place
and you should call both
AC_CHECK_GNUSTEP_LIBRARY and
AC_CHECK_GNUSTEP_FRAMEWORK

I don't feel strongly either way

though about naming conflicts e.g. libInterfaceBuilder vs 
InterfaceBuilder.framework
If we theoretically promote libInterfaceBuilder to a native-library

and take in to account the different ways people use GNUstep-make on 
apple
a) using gnustep
b) just using gnustep-baseadd/make

theres currently no way to stop gcc from looking in 
/System/Library/Frameworks etc
(well i believe there is in gcc svn) we can just add 
/path/to/GNUstep/System/Library/Frameworks
to the beginning with -F option

and if its found it'll link against the GNUstep one... before looking 
in system places
runtime is probably a whole other deal requiring environment variables 
and stuff

but yeah 1) and 2) look good
or a combination of 1) + AC_CHECK_FRAMEWORK used to implement 2)
