<h2>vxWorks TIMEZONE pentium</h2>
<p>If the name of the timezone has more than a few characters a crash can
occur on pentium vxWorks iocs. See ansiTime in the vxWorks reference manual
for details about TIMEZONE.</p>
<h2>GNU make version</h2>
<p>GNU make version 3.78.1 or later is required for builds. The README.html
file specifies version 3.70 but this version does not support the call
function.</p>
<h2>Borland build</h2>
<p>The borland-x86 build of base fails in src/ca because the Borland compiler
v5.5 does not support C++ placement delete. A fix is to add the following
code after the #include lines in ca/netIO.h and ca/syncGroup.h.</p>
<blockquote>
<code>// does the local compiler support placement delete</code><br />
<code>#if defined (_MSC_VER)</code><br />
<code># if _MSC_VER &gt;= 1200</code><br />
<code># define NETIO_PLACEMENT_DELETE</code><br />
<code># endif</code><br />
<code>#elif defined ( __HP_aCC )</code><br />
<code># if _HP_aCC &gt; 033300</code><br />
<code># define NETIO_PLACEMENT_DELETE</code><br />
<code># endif</code><br />
<code>#elif defined ( __BORLANDC__ )</code><br />
<code># if __BORLANDC__ &gt; 0x550</code><br />
<code># define NETIO_PLACEMENT_DELETE</code><br />
<code># endif</code><br />
<code>#else</code><br />
<code># define NETIO_PLACEMENT_DELETE</code><br />
<code>#endif</code><br />
</blockquote>
<h2>Visual C++ 6.0 Build</h2>
<p>The order of certain Microsoft header file includes must be rearranged as
follows in base/src/osi/os/win32/osdMutex.c and possibly also
base/src/libCom/osi/os/win32/osdEvent.c. This problem does not exist with
Visual C++ 7.0 (visual C++ .net).</p>
<p><code>// visual c++ 6.0 appears to be sensitive to the</code></p>
<p><code>// order of the following four lines</code></p>
<p><code>#define VC_EXTRALEAN</code></p>
<p><code>#define _WIN32_WINNT 0x400</code> </p>
<p><code>#include &lt;windows.h&gt;</code></p>
<p><code>#include &lt;winsock2.h&gt;</code></p>
