msys2 (mingw), error in 32 bit

[3rav]

I want to create a package for msys2 (mingw), for the mingw64 version the package was built without errors, but for the mingw32 version I have the following error:

That's interesting, thank you for reporting. I will try to look into it, but I'm not sure how to compile with 32 bit on my system. It seems complicated. And I expect that there will be several more issues apart from the multiple definition of 'lange'. You could try to just remove one of the multiple definitions, line 1728 or 1727, and see it that helps. Pieter
