Thanks for your hard work on improving the win32 compilation support!

On Windows XP Pro (actually a windows XP virtual machine running under 
vmware workstation), using mythbuildw32-1.zip, I get this:

$ ./mythbuildw32

I then tried cross-compiling in linux (Fedora 14 x86_64), and got the 
following:
*********************************************************************
Cross building MythTV fixes/0.24 for Windows using i686-pc-mingw32

The mingw32 <float.h> header must be patched to compile Qt.
