It worked for me.  I think the reason is I was prudent enough to
downgrade to libc-5.3.12 from libc-5.4.44.  Then and only then I
upgraded my distribution.  This way my old libc-5.3.12 RPM was
upgraded by the new one in the distribution.  The new one contained
not only libc-5 but also many other libraries compiled against libc-5.
Those who had upgraded to libc-5.4.x and failed to downgrade first
didn't get the new libc5 RPM and found their legacy applications were
using the glibc-compatible libraries in conjunction with libc5.

Returning to our subject: providing a libg++ 2.8 for libc5 would force
us to provide a special RPM for the day people will upgrade to a glibc
distrib.

The next Suse (don't remember if 5.2 or 5.3) will allow to run glibc
applications.  Caldera will go from 1.2 to 2.0 and the change in
version number hints to radical changes, one of them being probably
going glibc.
