-// system/core/android/log.h needs some work before it can be included in the
-// NDK. It defines a *lot* of macros that previously were usable names in NDK
-// sources that used android/log.h. As an example, the following file defines
-// LOG_TAG as a variable, but the variable name gets macro replaced if we use
-// the current android/log.h.

-// For now, we keep a copy of the old NDK android/log.h in legacy-ndk-includes.
