Re: Question about sysroot and fixincludes

Bionic headers prior to android-L (for L-preview) aren't changed
except for bug fixes since last major update in android-9 (gingerbread
era), the API level used to build all 32-bit NDK toolchains, so it
would be interesting to see how fixincluded differs should we use
different API level > 9.

Since JB, bionic is overhauled but not stable enough for NDK until
android-L.  It's very possible that fixincluded for andorid-9 is wrong
for android-L.  Do you have example?  We can fix up bionic headers for
all levels in NDK to make fixincluded consistent if not gone
