commit f246f54f18d380791cc60be4aea0fbc7253a9a20
Author: Dr. Matthias St. Pierre <Matthias.St.Pierre at ncp-e.com>

    Configure: accept Windows style compiler options
    
    Currently the Configure command only supports passing UNIX style
    options (`-opt`) to the compiler. Passing Windows style options
    (`/opt`) yields an error. Fortunately, the compiler accepts both
    types of options, nevertheless this commit fixes that discrimination
    of Windows users.
