But when I change the code to use the "static const WCHAR[]" the
compiler complains:
,-----
| factory.c: In function `AVIFILE_BasenameW':
| factory.c:163: warning: comparison between pointer and integer
| factory.c:163: warning: comparison between pointer and integer
| factory.c:163: warning: comparison between pointer and integer
`-----

So I have adjusted to use this:

static const WCHAR dotW = (WCHAR)'.';

The it compiles and works also for my. Is this okay? When it's I will
change it with my next patch, which still waits to be verified and
be submitted.
