>Description:
        Firefox fails to build, failing with a linker error. See 

http://bigbird.dohd.org:3021/NetBSD/pkgstat/20060325.0310/www/firefox/.broken.html

        for a full build log. 
>How-To-Repeat:
        Try and build firefox on a recent current
>Fix:
        Unknown. This bears a more than striking resemblance to pkg/32987, 
where glib2 failed with a similiar error. In that case, a mis-matched 
scope definition was to blame - amd64's linker is more strict in this than
others.

       I gave it a shot to locate the problem myself, but failed. The offending
call is made from inline assembly to an 'extern "C"' function defined just
above; commenting the call makes the linker happy (but is obviously not the
solution). My knowledge about gcc and C/inline assembly integration is just
not good enough to solve the problem :(
