base build fails due to non-fragile ABI and clang

[Riccardo Mottola]

Hi,

I just reconfigured make & base after about a fortnight, and base fails 
to build. I am using FreeBSD and clang:

 Compiling file preface.m ...
In file included from GSLocale.m:25:
In file included from ././common.h:35:
../Headers/GNUstepBase/GSVersionMacros.h:288:10: error: "You are building
      gnustep-base using the objc-nonfragile-abi but your gnustep-base 
was not
      configured to use it."
#        error "You are building gnustep-base using the objc-nonfragile-...

yet I have configured make with:

  $ ./configure --with-layout=gnustep --prefix=/ 
--enable-native-objc-exceptions --disable-non-fragile-abi CC=clang 
CXX=clang++ --no-create --no-recursion

I do not want the non-fragile ABI, I vastly prefer the fragile version 
for debugging (and perhaps speed, although I'm unsure) since I anyway 
recompile everything on FreeBSD.

What did change? I did not change the compiler and apparently nothing in 
the changelogs of make and base, although I see some changes.

Suggestions?
