getcontext on Linux PPC64

[Sergiy Kyrylkov]

According to the output I get on YDL 3.0 with 2.6.4 ppc64 kernel it is not
the case on my machine (Apple G5):

#include <stdio.h>
#include <ucontext.h>
#include <errno.h>

int main() {
  ucontext_t* pointer;
  int result = getcontext(pointer);
  printf("error: %s\n", strerror(errno));
}

[sergiy at zeta _test]$ rpm -qa | grep kernel
kernel-source-2.6.4-1.1321
kernel-2.6.4-1.1321
[sergiy at zeta _test]$ uname -a
Linux zeta 2.6.4-1.1321 #1 SMP Tue Mar 16 03:07:10 EST 2004 ppc64 ppc64
ppc64 GNU/Linux
[sergiy at zeta _test]$ gcc -m64 -mpowerpc64 contTest.c
[sergiy at zeta _test]$ file a.out
a.out: ELF 64-bit MSB executable, PowerPC or cisco 7500, version 1 (SYSV),

[sergiy at zeta _test]$ ./a.out
error: Function not implemented

Any suggestions?
