>Description:
        On NetBSD 3.0 (at least, yet to check others) graphics/libv4l
        generates a usage message from cc

>How-To-Repeat:
        I use pkg_comp and libkver with the NetBSD 3.0 release sets installed.
        NetBSD 3.0 (older gcc than expected perhaps) might be relevant
        I can't see how pkg_comp (or libkver) can be.

        Build graphics/libv4l - for me that was happening as a dependency
        of something else (hence the "medium" priority).

>Fix:
        Possibly this needs to use a newer gcc (from pkgsrc) on NetBSD 3,
        or perhaps the option is just an error, beats me.   I can't even
        guess what "visibility=hidden" might be meant to mean.
