[Harald van Dijk via Phabricator via cfe-commits]

hvdijk added inline comments.

Comment at: clang/test/Modules/cxx20-hu-04.cpp:22

+// RUN:  -fmodule-file=hu-02.pcm -o B.pcm -DTDIR=%t -verify

----------------
On Windows, when the path starts with `C:\Users\...`, I am seeing
```
error: 'warning' diagnostics seen but not expected: 

  Line 1: \U used with no following hex digits; treating as '\' followed by identifier

1 error generated.
```
Looking at this test, `TDIR` is only used as a FileCheck variable, can it just be removed from this line?
