Now that I have chilled for a while, how about making a smallish
change to MiG, add a new option, call it -file.  And to call mig with
a file name, you need to specify that option.  Then, we pass
_everything_ what we do not wish to handle to CPP, instead of making
special cases for stuff.

How about this?  This will ofcourse make things totally incompatible,
so all usages of MiG in glibc, the Hurd, GNU Mach and any other place
that uses MiG will need to be updated.

The patch is not tested, but it might work if I am not still mad.
