Roger Leigh commented on XERCESC-2099:
--------------------------------------

Part of the motivation for this work is investigation into occasional random {{ThreadTest}} failures on FreeBSD which I've been noticing for some time, but haven't yet pinned down a cause.

> Xerces-C currently supports POSIX and Win32 threading models with dedicated mutex manager classes.  C++ standards since C\+\+11 support native mutexes which will work on any supported platform.
> The attached patch adds a {{StdMutexMgr}} class and the necessary Autoconf and CMake logic to check if C\+\+ mutexes are available.  If not, it will fall back to the existing managers.
> On all but the most current compilers, it will continue to use POSIX/Win32 managers.  On the most recent compilers, which default to C\+\+14, the standard mutexes will be used.  On older compilers, the user must explicitly enable by setting {{CXXFLAGS=-std=c++11}} or later.

> - [appveyor|https://ci.appveyor.com/project/rleigh-codelibre/xerces-c/build/1.0.88]
> for build and test results.  You'll see that GCC on Linux is using POSIX mutex, while clang on MacOS X is using standard mutex.  On Windows, Cygwin uses POSIX mutex while MinGW and MSVC uses standard mutex.
