Nothing like following up one's own posting. :-} This bit is from the maintainer of the VMS port of GNU C, who ask me to post it... | Date: Tue, 02 Apr 1991 10:58:14 EST | From: Eric Youngdale <youngdale@v6550c.nrl.navy.mil> | | You can use the /NOCASE_HACK switch with the new compiler driver that | is now being distributed with gcc-vms.tar.Z compiler binaries. A version of | the driver itself is available via anonymous ftp from v6550c.nrl.navy.mil | in a compressed backup save-set. So, there's a new version of gcc binaries for VMS (gcc 1.39 and gas 1.38.1). It include's Eric Youngdale's improved driver routine, which has several bug fixes in addition to quite a few new options. The new distribution also has many C header files which were missing from the previous ones. The help file has also been expanded. It's available via anonymous FTP from the GNU archives on host "prep.ai.mit.edu" in directory "pub/gnu" and will presumably be picked up by the other gnu archive sites if it hasn't already been. The file gcc-vms.tar.Z is a compressed tar package (ie, Unix format 'saveset') which is nearly 2000 VMS blocks and must be transferred as binary data. No doubt it will also appear on the L&T and/or VAX SIG collection tape for the upcoming DECUS symposium. Pat Rankin, rankin@eql.caltech.edu
