Fwd: Boost compilation problems

Boost - Users mailing list
Hello, in attempt to build boost for android with more or less reasonable strict settings (-Werror) I uncovered some bugs which I cannot report on github because these projects have Issues disabled.

I will post them here in hopes they will eventually reach appropriate maintainers.

== ONE: boost.containers ==

clang-darwin.compile.c android-build/boost/bin.v2/libs/container/build/clang-darwin-5.0~x86/debug/address-model-32/link-static/target-os-android/threading-multi/alloc_lib.o
In file included from libs/container/src/alloc_lib.c:19:

== TWO: boost.serialization and monty python ==

The entire set of compile flags and NDK version can be seen in the provided snippets.

Thanks.
