base exception handling coherency

[Riccardo Mottola]

Hi,

today I am rebuilding on FreeBSD 10.1 / clang and even with a clean 
"configure" (no other options) I get this:

 Compiling file GSObjCRuntime.m ...
In file included from GSObjCRuntime.m:39:
../../Headers/Foundation/NSException.h:44:2: error: "There are two separate
      exception handling mechanisms available ... one based on the standard
      setjmp() function (which does not require special compiler 
support), and
      one 'native' version where the compiler manages the exception 
handling. If
      you try to use both in the same executable, exception handlers 
will not
      work... which can be pretty disastrous. This error is telling you 
that the
      gnustep-base library was built using one form of exception 
handling, but
      that the gnustep-make package you are using is building code to 
use the
      other form of exception handling ... with the consequence that 
exception
      handling would be broken in the program you are building. So, 
somehow your
      gnustep-base and gnustep-make package are incompatible, and you 
need to
      replace one of them with a version configured to match the other."

my gnustep-make was configured with:

./configure --prefix=/ --with-layout=gnustep CC=clang CXX=clang++

in the configure output I see:
checking whether the compiler supports native ObjC exceptions... no

is that the problem?

The configure check seems to fail for something stupid:

configure:6073: clang -c -g -O2 -x objective-c -I.   -fgnu-runtime 
-DGNU_RUNTIME -fexceptions -fo
bjc-exceptions  conftest.c >&5
conftest.c:10:10: fatal error: 'objc/objc.h' file not found
#include <objc/objc.h>
         ^
1 error generated.

is that expected?
