That was a wrong move.
Unless you exactly know what you are doing, and ready for the consequences,
adding Cygwin bins to windows PATH is a recipe for disaster.

No, it is exactly ./configure && make, no translation.

It means you have to set the environment to a value. This is not Cygwin
specific.

This has nothing to do with compiling at all, just the general Linux usage.

Try

    cd simp
    MROOT="$(dirname "$(pwd)")" make rs

Try a normal mail client.
