Comment (by osa1):

 What does that flag do? I think it's not documented (I checked the man
 page and
 user manual). Looking at the code, it seems like it doesn't write pragmas
 to the
 interface file (and ignores any pragmas that may make a different in the
 interface file, e.g. RULEs and UNPACK pragmas). I don't see how it's
 relevant to
 `-fno-code` though...
