As a consequence, the singleton implementation has to be made thread-safe.
Also implement the singleton pattern using a namespace, rather than a static
instance.
On Windows, this means that a POSIX threads implementation is no longer needed,
since C++11 threads are implemented using native Windows threads.
On GNU/Linux and macOS, POSIX threads are still used under the hood.
A new m4 macro (AX_CXX11_THREAD) is used to add the proper compilation
flags (instead of AX_PTHREAD).
- Use the -static flag when linking Dynare++, so that shipping libquadmath and
libgcc DLL in the installer is no longer needed.
- Use AM_CXXFLAGS and AM_LDFLAGS variables for changing flags, since CXXFLAGS
and LDFLAGS are user variables. Also, this avoids passing these flags down to
configure scripts in subdirectories.
- Check for the SZIP library in the configure test for the MatIO, this is
needed under MSYS2.
- Statically link MatIO and GSL in MEX files for MATLAB, this is needed under
MSYS2.
Note that dynare++ will only be built if configure finds ctangle, blas, lapack and pthreads
