RE: New Linux/libc5 CVSup client

Hi,

I'm the author of CVSup.  I'm really glad you cc'd me on your mail.

Great!  I've been meaning to try to get some newer binaries for
platforms I don't have.

It should fix that problem.  The checksum errors were caused by
some whitespace changes in RCS files that were introduced in recent
versions of CVS.  I made the checksumming algorithm for RCS files
ignore inconsequential whitespace differences, so this problem
shouldn't recur no matter what they do to CVS in the future.

There's still one potential source of checksum errors.  The very
newest versions of CVS support some new features such as preserving
file modes and handling links.  These are implemented using RCS file
extensions (see rcsfile(5) for details) which are not yet supported by
CVSup.  Luckily, it seems that few people use those extensions.  I am
going to implement a general scheme for handling them, hopefully for
the next release of CVSup.  Even if some files use the new extensions,
the current version will update them OK.  You'll see checksum errors,
but the "fixups" at the end will correct them (slower, of course).

This is the so-called "PM3" release of Modula-3, right?  I've made
the necessary changes to build CVSup under that version of Modula-3.
I've been holding off on releasing it because I'd like to get some
other new features into the program first.  But it's well tested on
a couple of FreeBSD mirror sites.  I put the sources up for FTP at:
   ftp://ftp.polstra.com/private/lockhart/cvsup-15.5.tar.gz

The MD5 checksum is 1f2466e83d06beb1ab2a2400515f9817.

You should be able to build it with "make M3TARGET=LINUXLIBC6".  I'd
love to find out whether it works OK under Linux, and fix it if it
doesn't.

I'm going to be on vacation next week, so I may be a bit unresponsive
to mail during that time.
