OK, this is strange: I changed epan/wslua/make-taps.pl to not declare v as _U_ (which
is obviously isn't: it's used in the next statement) and now we get a "set but not used"
warning but not before? Btw, on my Clang (XCode) system I do not get this warning/error.
Ideas what is going on here (compiler bug?)?

Thanks

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
