[distcc] building distcc-0.13 on irix

[Michael Santy]

IRIX does not have the wait4 function.  Therefore in dcc_collect_child() 
in exec.c, replace:

if ((ret_pid = wait4(pid, wait_status, 0, &ru)) != -1) {

with:

#if defined(__sgi__)
         if ((ret_pid = waitpid(pid, wait_status, 0)) != -1) {
           getrusage(-1, &ru);
#else
         if ((ret_pid = wait4(pid, wait_status, 0, &ru)) != -1) {
#endif

or however else you want it done.  This compiles and seems to work.

Thanks,
Mike Santy
