I've just had a play with this.

I haven't tested this properly, as I don't have access to a libc5 system
(well, I do, but I'd have to go online at daytime rates to access them; the
only system I've got at home is libc6). I suggest adding the following near
the bottom of scripts/os-type.

------
# In the case of Linux we need to distinguish which libc is used
# This is more cautious than it needs to be. In practice libc5 will always
# be a symlink, and libc6 will always be a linker control file, but it's
# easy enough to do a better check, and check the symlink destination or the
# control file contents and make sure.

case "$os" in
Linux)  if [ -L /usr/lib/libc.so ];
                if [ x"$(file /usr/lib/libc.so | grep "libc.so.5")"x != xx ]; then
                        os=Linux-libc5
                fi
        else
                if grep -q libc.so.5 /usr/lib/libc.so; then
                        os=Linux-libc5
                fi
        fi
        ;;
esac
------


Then the existing {Makefile,os.h}-Linux should be copied to -Linux-libc5,
and Makefile-Linux should be edited as

(I'd suggest that Berkely db should be the default on libc6 systems, as it
comes with libc6)
