Android's gcc 4.4 dumps many "the mangling of 'va_list' has changed in GCC 4.4" warnings for system headers we don't control and va_list code that does not care about a stable name mangling ABI. David Turner from the Android NDK team says : > there is no simple way to get rid of > the warning that I know of (trust me I tried). > The warning message comes from historical reasons. I believe it has been > completely removed from the GCC 4.5 sources, but we're not using this yet. > > For the record, the issue is that the mangling of 'va_list' has changed > between gcc 4.2.1 and 4.4.0 (due to a late corrigenda to the ARM spec, > previous versions of the toolchain mangled va_list the same a void*, which > was wrong). > > This however does *not* affect NDK-generated code because, very fortunately, > none of the stable ABIs exposed by the NDK depend on this mangling (this has > been checked carefully), so whichever toolchain you use, your code will run > on all Android systems.  https://groups.google.com/group/android-ndk/browse_thread/thread/9ab939743a968a83
