I rather support Chris that it should be covered by MONO_IOMAP.
I couldn't find the precise description that *.* should work like
that on MSDN, but if it exists, it would actually explain that
Directory.GetFiles() just reuses Win32 IO function that treats *.*
as to pick every file up.

If your explanation is regarded as correct, then the "path" argument
must be treated as case insensitive. Read "Remarks" section:

	The path parameter is not case-sensitive.

which does not apply to mono.
