Comment:
In #4496 I said:
{{{
On the Mac I have /usr/lib/libffi.dylib and /usr/include/ffi/*.h.
However, I can't see any mingw tarballs that seem likely to include it.
}}}
I can't see any sign of libffi in mingw64 either.
I really don't like having this be conditional, but I can't see a better
alternative, so I've applied the patch. Thanks.
I'm not sure if it's worth listing the new flag explicitly on
http://hackage.haskell.org/trac/ghc/wiki/Building/Using#Runtheconfigurescript
as it'll only really be of interest to a handful of packagers, and that
page only tries to list the most common flags, leaving the rest to
`./configure --help`.
