Cool, that makes sense. Thanks for the details.

I sent a v2 of those 2 patches.

FYI, I left the documentation that ptsname_r returns -1 on Tru64 and
HP-UX. I just remembered that this is also the case on FreeBSD where I
reported it and it was documented 2 years ago [1]. But it still hasn't
been changed [2].

Do you think that is worth documenting? We have to work around this in
Gnulib, for example, so applications can be portable.
