Unable to build with mingw 10.2.0

[sago35]

mingw 10.2.0 has been released on 2021/01/12.
However, the included gcc 10.2 was not able to build tinyg 0.16 and dev branch.
https://chocolatey.org/packages/mingw#versionhistory

I was able to build it by installing 8.1.0.

choco install mingw -Version 8.1.0
  or
choco install mingw -Version 8.1.0 --allow-downgrade

I'm using windows 10, and I'm building according to the following page

What is the error that you are getting with MinGW 10?

The log is below.

It looks like MinGW 10 doesn't support std::mutex. I'm not sure how to get it supported again, as LLVM relies on an up-to-date and fully supported compiler. Maybe some additional build flag is needed?

This is an error in the latest mingw-w64 package for chocolatey.

See https://chocolatey.org/packages/mingw#comment-5223930374

We should tell people to specifically install 8.1.0

@deadprogram glad we're not the only ones!

Unfortunately we currently depend on MinGW, MSVC is unsupported by the Go toolchain: golang/go#20982

Now we can build with the version available with choco install mingw.
The following version was installed when I tried it now.
And I was able to build correctly (make llvm-build CCACHE=OFF).

mingw 11.2.0.07112021 (gcc 11.2.0)
