[PATCH] In gcc 13, -Wall turns on -Woverloaded-virtual

[Corinna Vinschen via Cygwin-apps]

Also fix ambiguous method declaration by dropping a default parameter.
---
Hi Jon,

I'm not sure removing virtual from all Create methods really fits the
bill in all cases, are you?

I had a go at fixing this while keeping the virtuality of the methods
intact.  While at it it also occured to me that there's a tricky problem
for the compiler to differentiate the method

  Create ();

from the method

  Create (Window * = NULL, DWORD = 42);

I fixed this ambiguity by making the Window parameter a non-default
parameter.

What do you think?
