I suppose you could check for the gnustep base version (there are macros
for that) and only include the new code if gnustep-base >= 1.14.  Maybe
it's not worth the effort though.  Requiring gnustep-base >= 1.14 seems
reasonable. :-)

Not sure why - the old code to use GNUSTEP_PATHLIST to create the GNUstep
search path is still there ... so if it worked before, it should keep
working ? ;-)

Or maybe you mean that gnustep-make v2 + libFoundation wouldn't work - which
is right, but it's because libFoundation has not been updated to work with
gnustep-make v2. :-(

Thanks - you are right - thanks for adding this :-)

IIRC gnustep-base >= 1.14 requires gnustep-make >= 2.0.0

It might be needed to keep libFoundation working for the time being.

Actually, it might be worth checking if libFoundation works with gnustep-make
v2 - and if not, to make it work.  You mostly need a working implementation
of NSPathUtilities.  The current implementation based on GNUSTEP_PATHLIST
makes no sense with gnustep-make v2, but it should be easy to write a very
simple implementation where all paths are hardcoded in the library at
configure time; you won't have the ability to relocate things at runtime 
by editing the GNUstep config file, but otherwise it would be pretty enough.

I had a look but then found that I can't even regenerate libFoundation's 
configure
script using autoconf 2.61 (recursion limit exceeded) so that needs fixing 
first. :-/

Thanks
