Use g_get_host_name instead of gethostname and MAXHOSTNAMELEN This lets us punt thishost from owl_global. g_get_host_name implements the same localhost fallback, so we really don't need it. Also, Solaris gets upset about MAXHOSTNAMELEN when you define _XOPEN_SOURCE=500 without __EXTENSIONS__, if we ever care to get rid of that. (That said, glib's answer to this is lame. They just hardcode 100 and even forget to NUL-terminate the buffer; POSIX is apparently braindead and leaves truncation undefined. glibc is kind enough to give you ENAMETOOLONG.)
