Re: cygwin-latest: compile errors related to sockaddr_storage, dirent->d_type and dirent->d_ino

First of all, thanks for joining our discussion.  Being able to
hear from somebody from other project firsthand (not just listen
to somebody talking in his own changelogs and code comments, but
in actual e-mail exchange discussion) lets us put faces and
names to the entity "so far just one of the external projects to
us".

For reasons unknown, cygwin decided to use our sockaddr_storage.

I haven't looked at the proposed patch by Alex, so would not
comment on this part, but I'd appreciate your input.

For the other, probably unrelated, reasons, they decided to leave
declarations of DT_* macros in dirent.h without providing dirent->d_type.

I was wondering what the justification for keeping DT_* without
d_type myself.  What is the preferred resolution on this one
from your point of view?  I suspect removing d_type while
leaving DT_* was just a transient error and you would want to
remove DT_* as well, in which case the patch on this issue by
Alex would become unnecessary.

And on top of that, they removed dirent->d_ino (or probably replaced it
by __ino32, if at all).  BTW, can we somehow avoid using d_ino?  It is
referenced only in fsck-objects.c Anyway, to workaround this I put

COMPAT_CFLAGS += -Dd_ino=__ino32

It helps, but surely is not the solution.

I don't see how it could help since __ino32 is not actually filled in
with anything.  In fact, I'll rename the field to __invalid_ino32 to
make that clear.

I think renaming __invalid_* makes sense.  I'll see how we would
work this around on the git side to make things more portable.
