1// This test is for cases where we lookup a file by its 'real' path before we
2// use its VFS-mapped path. If we accidentally use the real path in header
3// search, we will not find a module for the headers.  To test that we
4// intentionally rebuild modules, since the precompiled module file refers to
5// the dependency files by real path.
