<p>See ExtUtils::MM_Unix for a documentation of the methods provided
there. This package overrides the implementation of these methods, not
the semantics.</p>

<p>Changes the path separator with .</p>

<dt><strong><a name="item_maybe_command"><strong>maybe_command</strong></a></strong>

<dd>
<p>Since Windows has nothing as simple as an executable bit, we check the
file extension.</p>
</dd>
<dd>
<p>The PATHEXT env variable will be used to get a list of extensions that
might indicate a command, otherwise .com, .exe, .bat and .cmd will be
used by default.</p>
</dd>
</li>
<dt><strong><a name="item_init_dirfilesep"><strong>init_DIRFILESEP</strong></a></strong>

<p>Using \ for Windows.</p>

<dd>
<p>Override some of the Unix specific commands with portable
ExtUtils::Command ones.</p>
</dd>
<dd>
<p>Also provide defaults for LD and AR in case the %Config values aren't
set.</p>
</dd>
<dd>
<p>LDLOADLIBS's default is changed to $Config{libs}.</p>

<p>Adjustments are made for Borland's quirks needing -L to come first.</p>

<p>Add MM_Win32_VERSION.</p>

<p>Add .USESHELL target for dmake.</p>

<dd>
<p>Changes how to run the linker.</p>
</dd>
<dd>
<p>The rest is duplicate code from MM_Unix.  Should move the linker code
to its own method.</p>

<p>Complicated stuff for Win32 that I don't understand. :(</p>

<dt><strong><a name="item_extra_clean_files">extra_clean_files</a></strong>

<p>Clean out some extra dll.{base,exp} files which might be generated by
gcc.  Otherwise, take out all *.pdb files.</p>

<p>All we send is -nologo to nmake to prevent it from printing its damned

<dt><strong><a name="item_oneliner">oneliner</a></strong>

<dd>
<p>These are based on what command.com does on Win98.  They may be wrong
for other Windows shells, I don't know.</p>
</dd>
</li>
<dt><strong><a name="item_cd">cd</a></strong>

<dd>
<p>dmake can handle Unix style cd'ing but nmake (at least 1.5) cannot.  It
wants:</p>
</dd>
<dd>
<pre>
    cd dir
    command
    another_command
    cd ..</pre>
</dd>
<dd>
<p><strong>NOTE</strong> This cd can only go one level down.  So far this sufficient for
what MakeMaker needs.</p>

<p>nmake 1.50 limits command length to 2048 characters.</p>
