Apologies, I think I may be missing something.

Do we have a gcc fix for "error: had to relocate PCH" which can be
applied to the pkgsrc gcc7 and gcc8? That would be great.

Otherwise the boost-libs workaround seems a good idea - either
extending to all NetBSD, or all NetBSD on gcc7 & gcc8 if we want to
not change the gcc5/6 behaviour (it could well be needed on more
os/arch/gcc combinations, maybe noone has tried building recent
boost-libs on vax -:p)
