I tried to compile iSDF 0.2.1 with the latest development snapshot of
Icarus (verilog-20060618) and it does not compile.

The first error complains about line 130 in isdf.cc:

  return vvp_delay_new(nvals, vals);


I compared the Icarus source code with that of version 0.8 and there has
been quite some rework done in vvp/delay.cc. That function
vvp_delay_new() is not there anymore and instead there are the two
classes vvp_delay_t and vvp_fun_delay.

So far I don't understand yet very much what is going on there. Just
from the code I was wondering whether a cheap trick would be to add a
constructor to vvp_delay_t to handle that function?
