Exactly. I am happy to submit a patch, but I cannot think of any
mechanisms besides:

  1. Calling `id`, which I suspect is very not portable.

  2. Writing a C program to check getuid(). That's portable for most
     Unixes. It looks like we already have a hacky wrapper on mingw that
     will always return "1".

Is (2) too gross?

Not overly gross compared to some existing test-*.c files, I would
say.

I wondered what 'perl -e 'print $>' would say in mingw, and if that
is portable enough, though.
