-// prefix these macro names either. This means that we'll collide with the

-// POSIX.1-2008 to the letter (since the macro definitions will be identical,

+// POSIX.1-2008 says we should define |st_atime| to |st_atim.tv_sec| (and
+// similarly for |st_mtime| and |st_ctime|). This is to provide (source)
+// backwards compatibility with older versions of POSIX.
+//
+// We could reasonably provide these macros on systems that are compliant with
+// POSIX.1-2008 (or later): even though they might collide with macro
+// definitions in the "real" <sys/stat.h>, it's okay since the macro definitions
+// will be identical. However, providing these macros on systems that aren't
+// POSIX.1-2008-compliant (like Android) leads to an intractable conflict. Thus
+// we provide prefixed macros instead.
