I've merged the first three patches, thanks. This one makes me nervous
as TARGET_OS has traditionally been a problematic variable and ?= hasn't
always done what you'd expect. This therefore needs a bit more testing
and investigation before we can merge it as I think there could be
problems exposed...

Cheers,
