--- Comment #3 from Nathaniel Shead <nshead at gcc dot gnu.org> ---
I haven't tested this particular issue yet to see if it's fixed in 16.  There
are still a few issues with GMF depending on 16 though; for the standard
library this can be worked around by using 'import std;' in most cases though
(which should also help build performance, as deduping headers from the GMF is
one of the more expensive parts of modules streaming).
