<li>The Berkeley DB 4.3 and 4.4 releases disallowed using the

|
|
--with-uniquename configuration option with the C++, Java, or RPC
|
|
|
|

Linux. [#14249]</li>

<li>Use libtool's "standard" environment variable names so that you can

set "AR" to "ar -X64" for example, and modify both libtool and the
|
|

it is no longer used. [#14726]</li>

<li>Fix a bug where, when a database is opened with the DB_THREAD flag
|

(the default in Java), and an operation in one thread causes the
|
|
|
|
|

be arbitrary data loss, as Windows zeros out pages from the read/write
