MinGW-w64 manual installation for MATLAB R2017b: Which installer options for threads and exception handling are preferred?

Our firewall prevents use of the MATLAB Add-on installer and the 'mingw-w64-install.exe' standalone installer [the latter cannot download its "repository.txt" manifest file].

Following instructions from https://stackoverflow.com/questions/38393755/mingw-w64-offline-installer, I have downloaded the eight available, pre-built GCC 5.3.0 [recommended] and 7.2.0 [latest] x86_64 installation .7z archives:

• x86_64-5.3.0-release-posix-seh-rt_v5-rev1.7z;
• x86_64-5.3.0-release-posix-sjlj-rt_v5-rev1.7z;
• x86_64-5.3.0-release-win32-seh-rt_v5-rev1.7z;
• x86_64-5.3.0-release-win32-sjlj-rt_v5-rev1.7z.
• x86_64-7.2.0-release-posix-seh-rt_v5-rev1.7z;
• x86_64-7.2.0-release-posix-sjlj-rt_v5-rev1.7z;
• x86_64-7.2.0-release-win32-seh-rt_v5-rev1.7z;
• x86_64-7.2.0-release-win32-sjlj-rt_v5-rev1.7z.

For use as a MEX/MBUILD compiler for MATLAB R2017b, should I unpack the archive with:

• threading model 'POSIX' or 'win32'; and
• exception handling model 'seh' [Structured Exception Handling] or 'sjlj' [Set Jump Long Jump]?

It seems to be: x86_64, 5.3.0, posix, seh.

Or at least this is the version reported by gcc.exe --version using the executable provided in the MinGW-w64 package for Matlab 2018a (but the version is the same for 2017b, as stated in https://www.mathworks.com/matlabcentral/fileexchange/52848-matlab-support-for-mingw-w64-c-c-compiler, and most likely so are the threading and exception options).
