Thanks for this explanation. As SUSv2 wants tv_sec to be time_t[1], would it be possible to change this to time_t on all but alpha? I guess alpha will not receive a switch to long anymore[2]. This would still require workarounds as you suggested below for alpha (nothing changes here), but would at least bring !alpha closer to standards compliance, which would be a good thing IMVHO. > > and this fails to compile on FreeBSD. > > You probably can just cast the tv.tv_sec to a time_t.

Regards, Andreas [1] http://www.opengroup.org/onlinepubs/007908799/xsh/systime.h.html [2] I read the instructions for sparc64, it that looked ugly and difficult. -- <TalisA> was macht man eigentlich auf einer linux-gamer lan ? hl server aufsetzen und freuen ? *duck* ^^ [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (FreeBSD) iD8DBQBDRrvHYucd7Ow1ygwRAjzQAJ40QsZ6hvdiUH7EwfOVR5DbgUJscACeNasm a1xfXIuUukYjSeCFrYq/g3c= =Cxa4 -----END PGP SIGNATURE-----
