openSUSE stable/SLE still defaults to gcc-4.8 (4.8.5), so depending on 4.9 or newer is a bit uncomfortable for those users (including me).
Bumping this to macOS 10.9 would get rid of the last known case of !HAVE_THREADSAFE_STATICS (cf. <https://cgit.freedesktop.org/libreoffice/core/commit/?id=aa2fbfc4faa24cf7ee5aa9afdafddbd536ac4fec> "Found out that Mac OS X 10.9 has working threadsafe statics"). What is unknown however is the status on Android and iOS. Having HAVE_THREADSAFE_STATICS everywhere would allow to clean up code, see e.g. <https://gerrit.libreoffice.org/#/c/35258/> "replace double-checked-locking with C++11 static initializer".
master-android$ grep -R THREADSAFE config_*/*.h config_build/config_global.h:#define HAVE_THREADSAFE_STATICS 1 config_host/config_global.h:#define HAVE_THREADSAFE_STATICS 0 But this is not set in stone, quite possibly the Android toolchain (NDK, which provides the C++ cross-compiler) can be updated to a newer version, and then the problem will go away. (See "with_android_ndk_toolchain_version=4.9" in configure.ac.) Regards, Miklos
