Sorry, I don't have visibility of a "accepted for checkin" marker. I'm happy
updating the 9098 patch.

That makes sense.

OK.  The patch would have to include the current epan/Makefile.am and
epan/libwireshark.def (to remove the plugin symbols from the base .def).  The
Windows build environment, however, uses epan/libwireshark.def directly. If
Gawk (from cygwin) is added to the Windows build environment, something similar
can be done with nmake.

Agreed.
