[omniORB] Python needed for Win32 VC8 binary distribution (4.0.7)?

As long as you are compiling for x86 (not x64) Windows you can download 
a binary version of Python 2.4.3 from http://www.python.org/ and take 
these files from the distribution:

	python24.dll
         copy_reg.py
         getopt.py
         ntpath.py
         os.py
         re.py
         sre.py
         sre_compile.py
         sre_constants.py
         sre_parse.py
         stat.py
         string.py
         types.py
         UserDict.py

Just copy all these files into the directory where omniidl.exe is located.

When you add an empty site.py file you can suppress the 'import site 
failed' message displayed by Python.

You only have to compile Python yourself when compiling for x64 Windows 
since no binary Python distribution for this platform exists for download.

In this case you need the attached patch since Python compiles out of 
the box with cl 14.00 (VS2005) but it crashes when starting up.

Best regards, Peter.
