[xml] Cannot compile with dlfcn (Win32)

["carlo\.bramix" <carlo bramix libero it>]

Hello.
I downloaded the current SVN version of LibXML-2 and I tried to compile it under Mingw32.
During compilation I discovered a bug that blocked the process.
The fact happens only if you install dlfcn package into the Mingw32 enviroment.
Into xmlmodule.c there is a conflict with two different implementations, so I fixed it by excluding the dlfcn 
support if the _WIN32 is detected.
After applying the fix, everything worked fine.
I hope it could be possible to commit this very simple fix, without the need of subscribing to bugzilla.
Keep up the good work.

Sincerely,

Carlo Bramini.
