BUILD FAILED: failed make distcheck

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?)?

The variable is set but not used. Nothing strange about the warning.
