[mythtv] [PATCH] Win32 frontend support

This patch should allow mythfrontend to run under Windows using cygwin.

Please could people test this, both on Windows systems and to check that it 
doesn't break the build on Linux machines.

The most significant change I've made is to move the definition of the 
gContext variable into libmyth - this is necessary in order to allow 
compilation under windows, and I don't think it should affect Linux users. 
Please correct me if I'm wrong.

Current issues:
 - no volume control
 - surround sound may or may not work properly
 - A/V sync currently doesn't work very well
 - not sure the themes are all working properly

Rough installation instructions are below.


	qt3-win32 (available from http://kde-cygwin.sourceforge.net/qt3-win32/ )
	mysql, freetype, lamemp3 etc

First thing that needs doing is getting qt to compile. Sources are 
available via sourceforge CVS - details are at 
http://kde-cygwin.sourceforge.net/qt3-win32 . The attached file qt.diff 
should fix a couple of bugs I found with this port. On the qt3-win32 page, 
it's stated that gcc2 is required to build the qt library - however myth 
won't work with this version. In order to get qt to compile on gcc3, a 
patch to ld is needed, available here: 
z2 . Note that this patch is only available for gcc3.2, not gcc3.3.

When configuring qt, it is important to turn on sql support, multithreading 
and jpeg support. The config command line I used is:

./configure -platform cygwin-g++ -plugin-imgfmt-mng -qt-imgfmt-jpeg -no-stl 
-system-zlib -qt-gif -system-libpng -system-libjpeg -qt-libmng 
-no-g++-exceptions -no-xft -no-xkb -disable-opengl -no-sm -no-xrender 
-thread -qt-sql-mysql

When qt is built, the attached patch file win.diff should be applied to a 
CVS checkout of mythtv. The audiooutputdx files should be placed in 
libs/libmyth, and the videooutput_dx files in libs/libmythtv.

To enable the win32 support, the settings.pro file should be edited
