[PATCH 0/4] add ptsname_r

[Eric Blake]

I propose adding ptsname_r; I'll push this in 72 hours if I don't
get any feedback.  [Among other things, I would expect feedback
to include whether ptsname_r should drag in locking, like our
strerror_r module, or just assume that no one else uses ptsname,
like our gmtime_r replacement in our time_r module.]

Patch 1 and 2 in isolation pass on Linux, Cygwin 1.7.9, and FreeBSD
8.2, but fail on Solaris 10.

Patch 3 fixes Solaris 10, but regresses on FreeBSD.

Patch 4 passes on all four platforms.

Oh, and cygwin CVS (will become 1.7.10) just added ptsname_r today,
although I'm still hoping that 1.7.10 will also add a patch to make
ptsname() thread-safe without ptsname_r.

Eric Blake (4):
  ptsname_r: new module
  ptsname_r-tests: new test module
  ptsname_r: port to Solaris
  ptsname_r: work around FreeBSD issue
