1.) Are they compatible with Microsoft OS's?

2.) If no to 1.) then why didn't the documentation think to mention that?

3.) If no to 1.) is at least possible to design and compile the .so files on a windows box?

4.) If so, is it possible to compile them under Visual C++? Borland C++? If so how?

5.) Will a mysql .so file compiled for use on a linux machine be usable on a Windows installation of MySQL on which the db project is being developed?

6.) What is the "global.h" include file referenced in the udf_example.cc and where can I find a copy?

7.) Why is it that whenever I post a message like this to a MySQL forum, either nobody answers or someone does and then the site is taken offline?
