gEDA-dev: Icarus Verilog, problem with output from $display?

[Timothy Miller]

It could be that I'm simply biased by what these mean in C, but, I'm
getting the same output from these two statements, and I don't expect
to:

$display("%06x", mywire);
$display("%6x", mywire);

If mywire==4, for the first one, I expect to see "000004", instead,
I'm seeing "     4".

Is there no way to get zero-padded output?  Or is this a bug in icarus?
