Hello,

I am using the GNAT GPL 2007.1 version on a Vista machine.

After this I installed the win32Ada 2007 bindings.

When I tried to build the examples, I am getting al lot of warnings:

Must I do something more before it will work? Or...??? How can I check
that the automatic configuration worked well?

And were is the help file of the win32 binding, could not find that
either.

Thanks in advance.

Greetings Antoine
