--- Comment #5 from John David Anglin <danglin at gcc dot gnu.org> 2011-02-19 17:30:27 UTC --- > Yes, so HP-UX 11 seems to do the right thing by default. So the problem is > HP-UX 10, which only provides the 3-arg form and not the standard one, right? I believe HP changed to the POSIX interfaces in HP-UX 10.30. Prior to that, only the 3-arg form is provided and not the standard one. The library build if I hack ctime.c and getlog.c, so these are the only build issues.
