Here's some changes, plus a wiretap/wtap.def file, to build wiretap as a DLL
on Windows. But after doing so, all 3 executables (edicap, ethereal, tethereal)
crash when I start them up (On win98: "This program has performed an illegal
operation and will be shut down.)

Any ideas as to why? I don't have my system set up such that I can run the MS
debugger on this.
