Is this right?

I'm tempted to say it should be `sizeof envvar'.  However my knowledge
of C is not clear enough to say whether that would evaluate to the
size of the array or the size of a pointer (8 bytes).

So perhaps it's safer to use something like:

  const size_t len = /* computed size */;
  const char envvar[len];
  /*  ... */
  snprintf (envvar, len, ...);

Rich.
