Security fix! Correct handling of seteuid() return value
See Debian bug #638002, reported by John Lightsey.
When possible the (already available) set_euidgid() function is used.
Additionally, it is unnecessary to change the identity when writing
into an already open file descriptor.
This should fix the problem.

| meillo@202 | 13 interface.c:55: warning: Using 'gethostbyname' in statically |
| meillo@202 | 14 linked applications requires at runtime the shared libraries |
| meillo@202 | 15 from the glibc version used for linking |
| meillo@202 | 16 |
| meillo@202 | 17 On NetBSD I no warnings were printed. |
