It's exactly like I suspected: a system header is #defining bswap64 as
a macro, causing a syntax error in my local definition. This is a
upstream bug twice over. First, nothing should be giving you
<machine/bswap.h> if you don't ask for it. Second, the manpage clearly
states that bswap64 is a function, so it's unacceptable to implement
it as a macro.
The first bug might be either NetBSD or OpenSSL's fault, I need to
figure out which. The second one is clearly NetBSD's fault. I'll deal
with the OpenSSL fix if a fix is needed. I'll need you to do the
NetBSD reporting since I don't have a NetBSD system and won't be able
to answer any follow-up questions if I file the ticket myself. For the
meantime, I'll probably have to work around the issue by renaming that
function in libaes_siv.
