[cfe-dev] Recursive includes not functioning?

[Kim]

Hi, I'm wondering why clang doesn't seem to be including files recursively:

Windows.h is in C:\Program Files (x86)\Windows Kits\8.1\Include\um and 
clang-cl automatically includes C:\Program Files (x86)\Windows 
Kits\8.1\includes yet Windows.h is not found?
