I installed this minor change to port genfile.c to Solaris 8.
2005-06-21 Paul Eggert <[EMAIL PROTECTED]>
* tests/genfile.c: Port to Solaris 8.
Include <signal.h>, for 'signal'.
(SIGCHLD) [! defined SIGCHLD && defined SIGCLD]: Define.
(child_exited, sig_child): Remove; not needed.
(exec_command): Use a prototype.
(main): Set SIGCHLD handler to default, not to sig_child.
And do this only if SIGCHLD is defined. This uses the
same pattern that src/tar.c uses.
