I wrote two test programs, both seem to work fine using libobjc2:

#import <Foundation/Foundation.h>

int main(int argc, char **argv) {

        NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init] ;
        
        int result = 0  ;
        
        NS_DURING
                [NSException raise:@"EXCEPTIO" format:@"FORMAT"];
        NS_HANDLER
                NSLog(@"%@", @"Trowing a test exception");
                result = 1      ;
        NS_ENDHANDLER
        
        NSLog(@"Leaving ...");
        [pool release]  ;
        return result   ;
}

The second test program using @throw seems to work:
#import <Foundation/Foundation.h>

int main(int argc, char **argv) {

        NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init] ;
        
        int result = 0  ;
        
        @try {
           if (argc > 1)        {
                @throw [NSException exceptionWithName:@"Trowing a test 
exception" reason:@"Testing the @throw directive." userInfo:nil];
           }
        } 
        @catch (id theException) {
                NSLog(@"%@", theException);
                result = 1      ;
        } 
        @finally {
                NSLog(@"This always happens.");
                result += 2     ;
        }
        
        NSLog(@"Leaving ...");
        [pool release]  ;
        return result   ;
}

both tested with libobjc2 and gnustep-make from svn. However, compiling and 
running sudoku, it hangs...

I'm now going back and reinstall using libobjc1, and will retest with my test 
program.
