Re: gEDA-user: icarus for-generate support

[Stephen Williams <steve@xxxxxxxxxx>]

Your example below is within the skills of Icarus Verilog, but
there was a very recent fix for exactly this problem. According to
my git logs, it was committed 6/11/2007, which is *after* the very
last snapshot. So try the current git. (It should be in the present
but stopped CVS as well.)
