Linux 2.1 handle SA_SIGINFO witch changes the prototype of
the signal handler (EXCEPTIONPROTO):
without SA_SIGINFO in sigaction:
int sig, struct sigcontext_struct ctx
int sig, struct sigcontext ctx
with SA_SIGINFO in sigaction (linux 2.1):
int sig, struct siginfo *sip, struct ucontext *ctx
I quick read includes on a linux-2.0 glibc2 config and
SA_SIGINFO is not defined. So, SA_SIGINFO is not handle
in glibc 2.0.6 (aka libc6).

compiling on 2.0 and running on 2.1 does work.
but compiling on 2.1 and running on 2.0 does not work.
