[PATCH] D65371: do not emit -Wunused-macros warnings in -frewrite-includes mode (PR15614)

[David Blaikie via Phabricator via cfe-commits]

dblaikie added a comment.

A test case would be good (in the clang/test directory - probably near/in the other tests for -frewrite-includes)

And does the same bug occur for other preprocessor-related warnings? Maybe it's not practical to disable them all this way & there should be a different solution? (or maybe we shouldn't fix these and users can pass -w to disable warnings when using -frewrite-includes?)
