Renaming a file or directory from e.g. foobar to FooBar (or any other casing change) should work, like on Windows, instead of being a no-op. Clobbering an existing file must also respect the new casing.
Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=46203 Signed-off-by: Gabriel Ivăncescu gabrielopcode@gmail.com ---
We just prepend the unix casing filename (without path) to the wineserver data before the actual unix filename, and a field `caselen` which is the length of this data.
