Dear Jerzy Grzegorek,

Are you sure the child immediately does an exec() ? vfork() is not
equivalent to fork(), so one cannot be blindly replaced by the other.
Since the whole test is dedicated to testing fork, I think it doesn't
make sense to build it. So, your previous patch was better, it is just
that your previous patch was completely removing the build of
test_fork, while it should be conditional on whether the platform
implements fork() or not.

Best regards,

Thomas
