+The following assumes you have the GNU-Win32 package, version b17.1 or
+later, installed and configured on your system.  See
+http://www.cygnus.com/misc/gnu-win32/ for details on the GNU-Win32
+project and the Cygwin32 API.
+
+1)  Copy the contents of the cygwin32 directory to the Perl source
+    root directory.
+
+2)  Modify the ld2 script by making the PERLPATH variable contain the
+    Perl source root directory.  For example, if you extracted perl to
+    "/perl5.004", change the script so it contains the line:
+
+	PERLPATH=/perl5.004
+
+3)  Copy the two scripts ld2 and gcc2 from the cygwin32 subdirectory to a
+    directory in your PATH environment variable.  For example, copy to
+    /bin, assuming /bin is in your PATH.  (These two scripts are 'wrapper'
+    scripts that encapsulate the multiple-pass dll building steps used by
+    GNU-Win32 ld/gcc.)
+
+4)  Run the perl Configuration script as stated in the perl README file:
+
+	sh Configure
+
+    When confronted with this prompt:
+
+	First time through, eh?  I have some defaults handy for the
+	following systems:
+	   .
+	   .
+	   .
+	Which of these apply, if any?
+
+    Select "cygwin32".
+
+    The defaults should be OK for everything, except for the specific
+    pathnames for the cygwin32 libs, include files, installation dirs,
+    etc. on your system; answer those questions appropriately.
+
+    NOTE: On windows 95, the configuration script only stops every other
+    time for responses from the command line.  In this case you can manually
+    copy hints/cygwin32.sh to config.sh, edit config.sh for your paths, and
+    run Configure non-interactively using sh Configure -d. 
+
+5)  Run "make" as stated in the perl README file.
+
+6)  Run "make test".  Some tests will fail, but you should get around a 
+    83% success rate.  (Most failures seem to be due to Unixisms that don't
+    apply to win32.)
+
+7)  Install.  If you just run "perl installperl", it appears that perl
+    can't find itself when it forks because it changes to another directory
+    during the install process.  You can get around this by invoking the
+    install script using a full pathname for perl, such as:
+
+	/perl5.004/perl installperl
+
+    This should complete the installation process.
