to which compiler should we step up to bundle with CB

[Miguel Gimenez]

There are a lot of users (and potential users) that still use W7 (even XP). In the company I work for about 80 % of the OS are W7-64, there are one XP and one W7-32, only a few are W10.

  - If you compile next release using the UCRT compiler they will have problems, unless the installer takes care of the needed MSW update.
  - If you bundle the UCRT compiler, they will need to install the MSW update when deploying their software to pre-W10 systems.

IMHO, MSVCRT will be with us many years.

 seems this works to for Win 7 (even that horrible Vista), only XP is out of the picture, which I really think is ok, we should drop old stuff some day.

Also, whatever compiler is chosen must be properly detected. 20.03 had problems detecting the bundled compiler.

currently nightly detected it without issues for me.

For me, I'm still using GCC with MSVCRT runtime. It works fine under Win7 and Win10. I haven't see someone using UCRT under Win7 before.

anyone any epxerience with this one, looks very promising : https://winlibs.com/

This is currently also my favourite compiler suite. However, the last version that was able to compile everything I have a need for was:
gcc-10.3.0-llvm-12.0.0-mingw-w64-9.0.0-r2
...but I will try version 13 - seems this might be a good one if it compiles wx32, indeed.

GCC 13 is important step for MinGW-w64 because it should support native Win32 threads. At least I can run simple test from the box.
Nixman just published GCC 13.1:  https://github.com/niXman/mingw-builds-binaries/releases  - it is kind of further development of the current 8.1.

It is me. 
I did it also on XP, with moderate success. 
By any way better to install UCRT if possible, even if soft is linked against MSVCRT.
