No, but the wrapper is built using the target compiler, with all of the
target flags.  We've talked about maybe filtering that command (e.g.
strip "-Werror" -- or "-WX" for cl.exe -- just so that slight problems
in the cwrapper don't bring someone's build to a crashing halt).  But so
far, nothing along those lines has happened.

'static volatile const char * MAGIC = ...'
        ^^^^^^^^^^^^^^
