Icarus Verilog has (and solves) all those problems. VPI modules
are dynamically loaded (works under Windows) and the package
provides iverilog-vpi to compile VPI/PLI modules for the user.
Really, it's not shockingly difficult if you stay away from the
M$ tools.

The Icarus Verilog Windows installer checks for the mingw32
compiler and marks the registry so that the iverilog-vpi program
can find it. Otherwise, it's no big deal. In fact, I am of the
opinion that it is best to *not* use Cygwin for anything you
are going to distribute, except as a last resort. The user
should be allowed to use Cygwin, but not expected to have it.

Really, dynamic linking is easy in every O/S out there, these
days. (With the possible exception of HP/UX. Ugh!)
