Fixes:

There is a support routine in the standard 4.4BSD C library
called "err()".  There is also a utility routine in
.../src/backend/bootstrap/bootstrap.c
with the same name.

Here's a patch that renames the pg95 routine to something a little
more sane.  As a bonus, one more bit of system-specific code leaves
the system...
