The problem is an apparent error in the /usr/include/sys/procset.h and /usr/include/sys/wait.h include files. cowbird:/usr/include/sys# diff -c wait.h.orig wait.h *** wait.h.orig Tue Feb 22 02:41:38 1994 --- wait.h Thu Aug 25 14:52:57 1994 *************** *** 298,304 **** #else _BEGIN_CPLUSPLUS ! extern int waitid(idtype_t, id_t, siginfo_t *, int); _END_CPLUSPLUS #endif /* _NO_PROTO */ --- 298,304 ---- #else _BEGIN_CPLUSPLUS ! extern int waitid(idtype_t, pid_t, siginfo_t *, int); _END_CPLUSPLUS #endif /* _NO_PROTO */ cowbird:/usr/include/sys# diff -c procset.h.orig procset.h *** procset.h.orig Tue Feb 22 02:41:44 1994 --- procset.h Thu Aug 25 14:43:52 1994 *************** *** 86,95 **** */ idtype_t p_lidtype; /* The id type for the left set. */ ! id_t p_lid; /* The id for the left set. */ idtype_t p_ridtype; /* The id type of for right set. */ ! id_t p_rid; /* The id of the right set. */ } procset_t; --- 86,95 ---- */ idtype_t p_lidtype; /* The id type for the left set. */ ! pid_t p_lid; /* The id for the left set. */ idtype_t p_ridtype; /* The id type of for right set. */ ! pid_t p_rid; /* The id of the right set. */ } procset_t; Also, if using gcc from the freeware disk, either replace syscall.h in the directory /usr/local/lib/gcc-lib/alpha-dec-osf1/2.3.3/include or replace with a link to /usr/include/sys/syscall.h.
