  Ah.

  I did think about writing a patch for that at one point.  OTOH, maybe rather
than having a -static-LANGRUNTIME for every language, maybe we want a flag
that modifies -static to link shared against libc/whatever system libs.  Or to
put it the other way round, maybe we want a generic "-static-runtime-libs" flag.
