New Linux/libc5 CVSup client

I've posted a new statically-linked CVSup client for linux-libc5 boxes
in:
 ftp://postgresql.org/pub/CVSup/cvsup-15.4.2-client-linux-libc5.tar.gz

I've noticed many checksum errors when using my older cvsup-15.2
installation, but have not yet had a real update to test this newer
package to see if it helps.

I used my existing from-sources Modula-3 installation to build it. That
form of Modula-3 installation may not be for everyone, since it took
over 200MB of disk space during the installation and ~50MB after. But...

I found an rpm-packaged version of Modula-3 which was trivial to install
on my glibc2 box, but have not yet been successful at building cvsup for
that machine. It looks like a configuration problem of some sort, since
it fails on the very first m3makefile statement. If anyone has an
interest in it I can give them the urls and point them at the CVSup
author; not sure if I'll have time to pursue it for a while...
