The odds of #define _WINNT_H working are incredibly slim :) You can't include the separate headers (winbase.h etc), you have to just include windows.h Windows defines IMAGE_* whether we like it or not, we can't stop it doing it, so the only reasonable solution is to change LLVM to have it's own set of constant...

In the Windows SDK headers, is the IMAGE_* defines in a separate file (e.g. winint.h)? Does the file have a guard against multiple inclusion? If so (and the guard was named _WINNT_H_), perhaps you can do something like: #define _WINNT_H_ #include <windows.h> So you would get everything except those file format defines. Of course, this would fail if other parts of the windows header rely on stuff declared in the the file being excluded. Alternately, could you include...

It was happening in a few files using COFF.h in LLDB for the windows branch (Windows.h is required for some typedef over Mutex, thread, socket, etc...). As said before, I am currently checking if it could be avoided (probably some refactoring will be needed). However I was wondering if it might not be easier to just avoid this clash at all by avoiding it in LLVM. Alternatively I could #undef
