Can't generate DLL on windowd under mSYS2

[bsaidus]

Hello.
I updated mSys2 to last version and when trying to compile the DLL, it gives me errors.
I corrected a declaration in libnet-structures.h (i__nt64_t => int64_t)
and it compiles but at the moment of generating a DLL it gives me these messages :
`

*** you link to this library. But I can only do this if you have a

I think the archive misses the .def file.

I hope someone with a Windowd machine can help out here, I'm UNIX all the way unless I dig out an old Windows XP ThinkPad from the closet ...

Latest msys2 have libpcap available via pacman. I've only looked at this ever so briefly, but it looks like the msys2 code path in libnet could be aligned more with a standard UNIX backend using descriptors, instead of the LPADAPTER used by Cygwin and the MSVC code paths.

Someone more versed in Windows would probably do a better job of this.
