[stunnel-users] patch to build stunnel 4.15 with VS2005

All--

I have created a patch that will allow stunnel 4.15 to be built with
Visual Studio 2005's command line environment. I have only tested it
with VS2k5, but it should work for all Visual Studio .NET versions
(that is, VS 7.0 or later).

After you apply this patch to the source tree, you will need to run
the makefile from a Visual Studio Command prompt
(Start->Programs->Visual Studio->Visual Studio Tools->Visual Studio
Command Prompt). From there, change the working directory to the
stunnel\src folder and execute the command "nmake -f vs.mak all".
After the build process has completed, you will have a working
stunnel.exe.

This patch will modify vc.mak to a working makefile for nmake
(mimicing the basic structure of mingw.mak), common.h to include a
couple missing headers for the I/O functions in pty.c, and env.c to
include the winsock headers under the Win32 environment (replicating
how it was done in common.h).

This patch that is a result of internal testing/development I've done
here at work and am releasing it to this list (and the stunnel
developers) so that these changes could possibly be included in future
stunnel releases. To the stunnel devs: if there's any additional work
that can be done to get this integrated by the next release, just
mention it.

The other day, I tried sending the patch to the list as an attachment,
but my message never showed up on either the mirt.net or google groups
mirrors. I can only assume it was rejected because of the attachment.
What follows is the full text of my patch file.
