 | during compilation of schilytools I found an incompatibility/conflict in the type declaration of 'idtype_t'.

 | The declaration of type 'idtype_t' in NetBSD in sys/types.h is:

 | typedef int idtype_t;
 | 
 | while the declaration according to POSIX is in sys/wait.h and has a different meaning.
 | 
 | Quote from POSIX documentation (see http://pubs.opengroup.org/onlinepubs/007904975/basedefs/sys/wait.h.html):
 | The type idtype_t shall be defined as an enumeration type whose possible values shall include at least the following: P_ALL P_PID P_PGID
 | 
 | End quote
 | 
 | Please note that sys/wait.h unfortunately also includes sys/types.h.

 Well, even if we add these constants the program will fail because we'll be
 missing the waitid() call which is probably trying to use. It should autoconf
 for the existance of the call directly.
