Some tools differ from their Linux equivalnts and also from older versions

[w-bruns]

I use MSYS2/MinGW64 to compile Normaliz (see https://github.com/Normaliz/Normaliz) with all auxiliary packages. I managed to do this in the spring of 2022, and that installation can still be used.

I have a new machine now and installed MSYS2/MinGW64 some days ago. I think I can compile Normaliz with updated auxiliary packages again, but there were some obstructions:

• The new make = mingw32-make.exe doesn't seem to work properly. For this reason I copied the 2022 make.exe to the new installation.

• The same applies to diff.exe and cmp.exe.

• Because of changes in the source codes of Flint and e-antic, ld.exe stumbles on a doubly defined function, appearing both in Flint and e-antic /see Upstream {fmpz,fmpq}_poly_extra flatsurf/e-antic#153). This holds for the old as well as the new version of ld.exe. By patching the code of e-antic I could overcome this problem. However, the loinkers of Linux and MacOS accept the duplication without a complaint.
