@Panke updated dlang/dmd pull request #13755 "Fix Issue 21844: makedeps contain
non-existing files" fixing this issue:

- Fix 22708 - Extend semantic for switch statements with invalid values
(#13617)

  Only omitting the cast allows further semantic to perform the expected
  checks and transformations. This allows for better error detection that
  were not reported before and also avoids invalid errors due to missing
  `optimize` calls.
