--- Comment #33 from Greg Chandler <chandleg at wizardsworks dot org> ---
for (n_commands = 1, i = 0; argbuf.iterate (i, &arg); i++)
fprintf (stdout, "%d: %s\n", i, argbuf[0]);
With the following inside the following if: if (arg && strcmp (arg, "|") == 0)
fprintf (stdout, "%d: %s#%s\n", foobar, commands[n_commands].prog,
commands[n_commands].argv);
Yields:

gcc: fatal error: cannot execute1 'cc1': posix_spawnp: No such file or
directory
compilation terminated.
So what we see is 15 iterations of the loop: for (n_commands = 1, i = 0;
argbuf.iterate (i, &arg); i++)
But Not a single match on the if statement looking for a pipe, which I guess is
a good thing at the moment.
I numbered all the "cannnot execute" errors as well, to help trace that down,
and this is exiting from the same function (execute):
if (errmsg != NULL)
{
errno = err;
fatal_error (input_location,
err ? G_("cannot execute1 %qs: %s: %m")
: G_("cannot execute2 %qs: %s"),
string, errmsg);
}
So I'm going to start working backwards from here, and see what that yields.
