infos on compiler flag

[Perrone Alessandro]

Hi all
I am compiling a very simple program written in objc 
(http://www.slip.net/~dekorte/Objective-C/Documentation/5_SampleCode/SampleCode1.html), 
Here it is the result of compilation
--
gcc -fgnu-runtime main.m printer.m -o test
main.m:0: Assertion "flag_next_runtime" failed
printer.m:0: Assertion "flag_next_runtime" failed
[localhost:~/objc-sample] alex% gcc -v
Reading specs from /usr/libexec/gcc/darwin/ppc/2.95.2/specs

gcc3 -fgnu-runtime main.m printer.m -o test
main.m: In function `main':
main.m:6: warning: return type of `main' is not `int'
main.m: At top level:
main.m:14: internal error: Bus error

But If I use the -lobjc flag,
gcc3 -lobjc main.m printer.m -o test
main.m: In function `main':
main.m:6: warning: return type of `main' is not `int'
[localhost:~/objc-sample] alex% ./test
Hello World!
[localhost:~/objc-sample] alex%

Any hints?
Regards.
