[xml] windows binary with different calling conventions

["Peter Jacobi" <pj walter-graphtek com>]

Dear Gustav, Igor, All,

Isn't this a problem, inherently caused by the distribution of a Win32 
binary DLL?

Without distributing the binary, everybody adds libxml to his project, and 
compiles with his favourite flags and it will work.

So, by the gracious act of sponsoring a Win32 binary, Igor got all these 
complaints of MT/ST and stdcall/cdecl.

So, a not completely tongue-in-cheek solution, is to stop the distribution 
of the Win32 binary DLL.

Another solution would be (at least) four Win32 DDLs for each version.

Best Regards,
Peter Jacobi
