The non-reentrant gethostbyXXXX() functions deadlock if called recursively, for |
| 2 |
example if libldap needs to be initialized from within gethostbyXXXX() (which |
| 3 |
actually happens if nss_ldap is used for hostname resolution and earlier |
| 4 |
modules can't resolve the local host name), so use the reentrant versions of |
| 5 |
the functions, even if we're not being compiled for use in libldap_r |
