Can you give me little more hints on this, please? I've run the verbose build
and it have given me the following:
```

There is the file named `uchar.h` in the directory `C:\Program Files
(x86)\Windows Kits\10\include\10.0.17763.0\ucrt`, and it contains the typedefs
for `char16_t` and `char32_t`, but I can't figure out, how the compiler could
see it.
An interesting thing is that the compilation with the same command in the same
console completes successfully:
```
C:\Work\llvm\build_x64\bin\clang-cl.exe -m64 /Od /GS- /GR- /Z7 -Xclang
-fkeep-static-consts /c
/FoC:\Work\llvm\build_x64\tools\lldb\lit\SymbolFile\NativePDB\Output\tag-types.cpp.tmp.exe-tag-types.obj
C:\Work\llvm\tools\lldb\lit\SymbolFile\NativePDB\tag-types.cpp
```
