Right, similar issue.

>hard part is what to set $TMPDIR to.

Agreed.

If I get a C API I can just call, I would put it into main.c in mksh
(set TMPDIR to that value, unless we import it from the environment
already).

Otherwise, something should ensure that $TMPDIR is set whenever mksh
is called. Since the shell can be called various ways (during boot,
adb, from a local application), this is pretty complicated; I’d suggest
adding code to bionic which I can call might be easier.

Hrm. I’ll have to see if linux-kvm works inside a linux-kvm VM.
IIRC, this works with AMD CPUs. What is the “magic invocation”
to build for that, instead of for emulator (which I used to be
as close to upstream as possible)?

Title:
  "mksh -v" should display mksh's version number, plus the attached

Bug description:
  It's customary in the Unix world that "-v" or "--version" displays a
  program's version. If someone is logged into an Android device, you
  want to make it easy for them to find out which shell is installed.
  How can you do this? One way is to offer a "-v" option which will tell
  them the answer (and will also tell them mksh's version number).

  May I suggest that, if the user runs "mksh -v", then mksh should echo
  the following to stdout, after which it should immediately exit.
