Subject: [PATCH] tdb: Fix invalid syntax in tdb.h
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Defining _PUBLIC_ in the same way as in talloc.h resolves an issue with
a previous fix for Solaris Studio compiler 12.4 that prefixed all calls
in tdb.h with _PUBLIC_.  Thanks to Lukas Slebodnik
<lslebodn@redhat.com>.
