I think you brought up quite a few good points (also in the part that I did not quote).

The part I quoted brings up one particular aspect that I would like to drive home a little more: the purpose of naming, and the historical reality. ("hysterical raisins" comes to mind.)

In Git, we have an awful lot of references to MINGW, which is the name of a project that tried to allow compiling software targeting pure Windows (i.e. the Win32 API, without any POSIX compatibility layer) with the GNU C compiler.

As many open source projects require more than just the GNU C compiler (e.g. a Bash to run ./configure), there is also MSys, which is a minimal fork of a then-current version of Cygwin, originally intended for the sole purpose to support building MINGW software.

To make things more confusing, at some stage the mingw-w64 project was started (not as a fork of MINGW, AFAIU), to address the notable lack of 64-bit support in MINGW, and later the MSYS2 project was started, based on mingw-w64, to address the same issue with MSys (also not forking, but instead starting from scratch).

Back in 2006, when I started to port Git to Windows, I made use of MINGW and MSys (and I abused MSys by shipping their Bash with Git, which was distinctly not intended a usage of their Bash). Hannes Sixt picked up when I stopped having access to a fast Windows machine, and kept my naming: compat/mingw.c.

Now, Philip Oakley, Jeff Hostetler and a few other developers spent quite a bit of effort to make Git compile also with Visual C, and of course the reused parts of compat/mingw.c (whose name now does not make too much sense anymore, except in historical context).

Likewise, when I switched to MSYS2/mingw-w64 with the major version jump to Git for Windows 2.x in 2015, I no longer use MINGW to compile *anything*.

I hope that this illustrated a little bit how our names came about.

Of course, we could now spend some time to change the names to reflect more the product and brand names involved. There does not seem to be any really compelling reason to do so, though. And I'd rather spend my time developing exciting features. But that's my preference for my time, so if anybody comes along, making a strong case for renaming, in a well-crafted patch series, who am I to say no to that.

Ciao, Dscho
