I don't think that's important. Either the thing is a drop-in replica of
getpass, or it is not. In the former case, it's OK for it to be
transparent that it has been replaced. In the latter case, it should not
be a #define replacement at all, but should be its own alternative in
compat/terminal.c (just like HAVE_DEV_TTY is).  From my reading of
getpassphrase, it does seem to be a drop-in replacement.

So I'm OK conceptually with the patch if we can't do any better. But
getpass still sucks. It doesn't handle echoing, and it may or may not
fall back to reading from stdin if the tty isn't available (which is
disastrous for remote-curl, whose stdin is speaking the remote-helper
protocol to git). So I'd really prefer to make HAVE_DEV_TTY work with
Solaris if we can.

I'm happy to spend a few cycles on it.  I don't have access to any real
Solaris boxes these days, but I imagine I can get OpenSolaris running
under VirtualBox without too much trouble...


PS If we do go the getpassphrase route, does it make sense to introduce
   HAVE_GETPASSPHRASE? We usually try to provide one layer of
   indirection by naming our #defines after features, and then
   connecting systems to the feature defines via the Makefile. But maybe
   Solaris is the only system that has getpassphrase.
