Seems that *did* fix it, which opens a whole new set of questions about
how much you can trust msys' make.  However, the latest seahorse results
show we still have a bug or two:
    oidjoins             ... ok    type_sanity          ... ok    opr_sanity           ... ok
test geometry             ... server stopped
diff command failed: "diff -w "./expected/geometry.out" "./results/geometry.out" >"./results/geometry.diff""
make: *** [check] Error 2

What I think happened here is that diff reported a difference and
pg_regress misinterpreted the exit status as being a hard failure.
Can someone check on whether it's possible to tell the difference
between these cases with Windows diff ?
