0.7

BREAKING: Removed the use of the compatibility library to automatically generate macros and workaround for older compilers. The important compatibility workarounds like the __builtin_clz extension are still used, but workarounds for missing C++11 library features have been removed. In particular, the library now requires compiler support for noexcept, constexpr, alignof and thread_local. This means that GCC 4.8 and Visual Studio version 12.0 (both released in 2013), are now longer supported.

Adapter

BREAKING: Remove Mutex support from allocator_reference and consequently from std_allocator, allocator_deleter, ... Embedding the Mutex with the reference was fundamentally broken and unusable to ensure thread safety. Use a reference to a thread_safe_allocator instead, which actually guarantees thread safety.

Allocator

Add ability to query the minimal block size required by a memory_pool or memory_stack that should contain the given memory. Due to internal data structures and debug fences this is more than the naive memory request, so it can be computed now.

Bugfixes

more CMake improvements for cross-compiling, among others
bugfixes to support UWP (#80), VxWorks (#81) and QNX (#85, #88, among others)
better support missing container node size (#59, #72, among others)
fix alignment issues in debug mode
