=head1 SYNOPSIS
-These are instructions for building Perl under Windows 9x/NT/2000/XP

+These are instructions for building Perl under Windows 2000 and later.
=head1 DESCRIPTION
particular, you can safely ignore any information that talks about
"Configure".
-You may also want to look at two other options for building
-a perl that will work on Windows NT: the README.cygwin and
-README.os2 files, each of which give a different set of rules to
-build a Perl that will work on Win32 platforms. Those two methods
-will probably enable you to build a more Unix-compatible perl, but
-you will also need to download and use various other build-time and
-run-time support software described in those files.

+set of rules to build a perl for Windows. This method will probably

This set of instructions is meant to describe a so-called "native"

+port of Perl to the Windows platform. This includes both 32-bit and
64-bit Windows operating systems. The resulting Perl requires no
additional software to run (other than what came with your operating
system). Currently, this port is capable of using one of the
following compilers on the Intel x86 architecture:
- Borland C++ version 5.02 or later
- Microsoft Visual C++ version 2.0 through 7.0 (and possibly later)
- MinGW with gcc gcc version 2.95.2 or later
+ Borland C++ version 5.02 or later
+ Microsoft Visual C++ version 6.0 or later (*)
+ Gcc by mingw.org gcc version 3.2 or later
+ Gcc by mingw-w64.sf.net gcc version 4.4.3 or later
-The last of these is a high quality freeware compiler. Use version
-3.2.x or later for the best results with this compiler.
+(*) NOTE: Support for Visual C++ 2010 is not yet complete. This latest
+version of VC++ introduces some new C<errno.h> constants which conflict
+with Perl's current setting of them to match the corresponding WSAE*
+constants' values. Until this issue is resolved you will see several test
+failures (in F<cpan/autodie/t/flock.t>, F<dist/IO/t/io_multihomed.t >,
+F<dist/Net-Ping/t/450_service.t> and F<dist/Net-Ping/t/510_ping_udp.t>)

The Borland C++ and Microsoft Visual C++ compilers are also now being given
away free. The Borland compiler is available as "Borland C++ Compiler Free
Command Line Tools" and is the same compiler that ships with the full
"Borland C++ Builder" product. The Microsoft compiler is available as
-"Visual C++ Toolkit 2003" or "Visual C++ 2005 Express Edition" (and also as
-part of the ".NET Framework SDK") and is the same compiler that ships with

+Also, the trimmed down compiler only passes tests when USE_ITHREADS *= define
+(as opposed to undef) and when the CFG *= Debug line is commented out.
This port fully supports MakeMaker (the set of modules that
is used to build extensions to perl). Therefore, you should be
able to build and install most extensions found in the CPAN sites.

-A number of extensions specific to the Win32 platform are available

-cannot be built using the generic steps shown in the previous section.

for a reasonably definitive list of these differences.
Not all extensions available from CPAN may build or work properly
-in the Win32 environment. See L</"Building Extensions">.
+in the Windows environment. See L</"Building Extensions">.
Most C<socket()> related calls are supported, but they may not
behave as on Unix platforms. See L<perlport> for the full list.
-Perl requires Winsock2 to be installed on the system. If you're
-running Win95, you can download Winsock upgrade from here:
-
-http://www.microsoft.com/windows95/downloads/contents/WUAdminTools/S_WUNetworkingTools/W95Sockets2/Default.asp
-
-Later OS versions already include Winsock2 support.
Signal handling may not behave as on Unix platforms (where it
doesn't exactly "behave", either :). For instance, calling C<die()>
or C<exit()> from signal handlers will cause an exception, since most
-implementations of C<signal()> on Win32 are severely crippled.
+implementations of C<signal()> on Windows are severely crippled.
Thus, signals may work only for simple things like setting a flag
variable in the handler. Using signals under this port should
currently be considered unsupported.
