> I agree with you, but unlike {{{Rts.h}}}, libffi headers {{{ffi.h}}} and
{{{ffitarget.h}}} are dynamically generated by
{{{libffi/build/configure}}} so the correct fix would be to treat them in
a similar way as we treat {{{ghcautoconf.h}}} and {{{ghcplatform.h}}}.
That is, let {{{libffi/ghc.mk}}} copy them directly into {{{includes}}},
not into {{{rts/dist/build}}}. Do you think this is appropriate? If so,
I'll rewrite my patch.
I think the right thing to do is to add `TOP"/rts/dist/build"` to
`include-dirs` in `rts/package.conf.in`. We already have `TOP"/includes
/dist-ghcconstants/header"` there, for a similar reason.
