Ok thanks, so it can at least be discovered. On my osx machine I have cc in there, so I guess this means the C toolchain ?

Assuming we are accessing this from a build system implemented in OCaml, I guess this fails in cross-compilation settings since you will get the values of the build-os OCaml compilers in there.


> The mingw compiler already use the form w64 for the host, so that the compilers "fake" a cross-compiling triple (e.g. i686-w64-mingw32-gcc and x86_64-w64-mingw32-gcc). Perhaps that would be better?
I don't understand what you are proposing here. Did you say we should use "mingw32" as an OS value to denote the mingw ports ?  

Best,
