Not all systems which have setreuid() in the C library really support
it, e.g. 4.4BSD or 4.4BSD-Lite derived systems. On those systems, you
want to use seteuid()/setegid() when you want to change identities.
I can point you to updated krb4 ticket file code which uses seteuid() to
do what I believe is the Right Thing for setuid programs, as far as
getting the file owned by the right user is concerned.
