Compile SSL support to Sylpheed-Claws / Win32 :

Note: As I dont have an SSL email provider, I was only able to compile it - the
testing is now up to you... much luck :)

1. Get the openssl library. 
You might either compile from the sources (openssl-engine-0.9.6b.tar.bz2), or
install the precompiled libraries (claws_w32_ssl_dev.zip).

Install precompiled libraries:
Unpack the files to the root of your sylpheed-sourcetree (e.g. "C:\", if your
sources are in C:\dev\...). It should put the header-files (*.h) to
\dev\include\openssl and the libs to \dev\include\ .
Then chdir to \dev\include\proj and apply the patches to sylpheed.dsp and
src\config.h using:
	patch -p0 < claws_ssl.diff

If your patch program fails, or you install from the openssl sources, then
manually add following files:

1. src\sonfig.h :
   locate the following line and change it
	from	#undef USE_SSL
	to	#define USE_SSL 1

2. sylpheed.dsp :
   Add these lines to the list of included files
	# Begin Source File

	SOURCE=..\..\lib\ssleay32.lib
	# End Source File
	# Begin Source File

	SOURCE=..\..\lib\libeay32.lib
	# End Source File

You will also need libeay32.dll and ssleay32.dll within sylpheeds search path,
to run sylpheed. The precompiled package puts them to \sylpheed\bin.
