=> The Microsoft C compiler has been located in the environment which suggests opam
   is running either from a Tools Command Prompt or from another wrapper which is
   updating the environment variables.

   opam has not altered these environment settings, but you will need to ensure
   that future invocations of opam are done from the same environment, or the
   compiler will be unavailable.
