“archive has no index” error when unit testing on native with Mingw-w64

[robmaxtech]

With a unit testing project as native test using MinGW64, installed as in the doc, I encountered a mingw32/bin/ld.exe: .pio\build\native.... .a: error adding symbols: archive has no index; run ranlib to add one error message. Via this post I found that MinGW 13.2 seems to be the reason for the problem; after downgrading to MinGW 12.2.0.03042023 solved the issue. (installation via chocolatey; I assume it works also with other installation ways) Maybe this should be mentioned in the doc.
