Looks just fine, and welcome to notmuch!

Could you resend these as separate patches, each patch fixing a single
type of warning? That would make it more clear what the code is doing.

I don't like the gratuitous conditional here. It clutters the code and
make is less clear. If we're just trying to squelch a warning about an
unused return value from a function, then I think I'd rather see:

	ssize_t ignored;

        ignored = write (2, msg, sizeof (msg) - 1);

What do you think?
