OI don't really understand this one.
Well the reason for the native library stems from the essentially obvious fact that native libraries are libraries on non-Darwin systems and frameworks on Darwin system (well unless your name is Matt and you've implemented native frameworks in GNU/Linux and GNU/Hurd ;-) ). So when /checking/ for projects that are native library projects we could duplicate -make's logic to decide to use _LIBRARY or _FRAMEWORK in every configure.ac script, or we could add the code to a macro supplied by -make that could be used by all and that would be updated in sync with -make when/if other platforms support frameworks. But I actually want to clarify what I meant with the third option for the configure issue... My goal is to have ./configure of GDL2 identify whether libGorm is installed/usable so it can decide whether the palette should be build or not. (The servers I deploy my GSWeb App on do not have X/AppKit/GORM but use GDL2 & GSWeb... currently I need to disable building the palette explicitly via configure option.) Now most configure checks like AC_CHECK_LIB work by trying to build a minimal example code snipit and link it against the library. For GNUstep we probably need a lot of the features of -make to accomplish this. So to avoid duplicating -make in new configure macros, one could imagine creating config/gorm/ subdirs which contain a minimal test.m file and a minimal GNUmakefile (or have them generated by the new macros). And then have ./configure invoke 'make' in this subdirectory to see if this minimal project can be built/linked to decide whether to set a ./configure variable or not. OT1H, I feel this might be "shooting at pigeons with canons" (is that expression used in English?), yet OTOH it might be the only reasonable approach without duplicating -make features in configure macros especially for the cross-compilation case.
