I'm not sure it has 6 on one single platform? I was thinking of C vs stdcall but I could accept changing it to Windows has at least two if you want to count fastball and vectorcall.

The table here lists quite a few, but when I mentioned "closer to 6" I had a few Pascal / Delphi mangled in my head thinking that they were Windows-specific and not Pascal-on-Windows-specific, sorry.

I had to use stdcall and safecall for COM programming in 2000s, and somehow thought they are Windows things (turns out safecall was a Borland invention).

This has been done I think.
