I never heard about TDM except from you.

Somehow, I installed msys2 many times, using 2 or 3 different methods
and it worked every single time. It's huge download, but it works.
There were cases where I had problems installing additional packages on
top of msys2, but they were always caused by idiotic policies of
corporate IT. At my personal systems it was always flawless.

The size you mentioned in the previous post is suspiciously similar to
the size VS2013 statically linked binary.

That is smaller than statically linked 32-bit VS2013 (73,216 bytes).
But a lot bigger than 6,144 DLL-based VS2013 32bit binary.
