They have a non-standard anonymous account configuration, and I could not remember how to get in so I could check it this morning. It would be safe to look at the dates on the files on rdss - if they are more than 6 months old, it is safe to assume that they are old. Admittedly it would be nice to be able to distribute gcc-vms as a compressed backup save-set, but there are a couple of compelling reasons why this is not done. 1) Backup save sets are larger - there seems to be more information stored there, and as a result there is more data that needs to be transferred. 2) You need a special version of LZDCMP and LZCOMP to compress/decompress a backup save-set, since the RMS file attributes must be set properly before backup will recognize the save set. 3) UNIX does not have any capability to unpack a backup save-set, while there are detar utilities floating around for VMS. Some people want to decompress and unpack the distribution on a unix machine, and then ftp the resulting files to the VMS machine. 4) Compressed tar format is used for everything else on prep. If you actually ordered the tape from the FSF, you would get a tape with four backup save-sets on it (executables (equ to gcc-vms.tar.Z), gcc sources, gas sources, and bison sources). ------------------------------------------------------------------ Eric Youngdale INTERNET: YOUNGDALE@V6550C.NRL.NAVY.MIL Naval Research Lab SPAN: 11.13 (or 11277::) Washington, DC FLAME-NET: NLA0: Disclaimer: The opinions expressed herein are my own and not necessarily those of my employer. -- MSEN Archive Service file verification prep.ai.mit.edu -rw-r--r-- 1 14910 wheel 1049477 Apr 4 12:37 /pub/gnu/gcc-vms.tar.Z found gcc-vms ok prep.ai.mit.edu:/pub/gnu/gcc-vms.tar.Z
