XScreensaver 5.04 does not build on amd64 with gtk+-2.12.7. Also tried with 5.02. The installation halts at exactly the same place. It can be seen in the URL posted above.

xscreensaver has an "interestingly" named macro called "STFU", and it sticks that in front of a g_assert on the referenced line (drivers/demo-Gtk.c line 1130). STFU expands to __extension__, to shut up pedantic warnings or something, but g_assert expands to "do ... while ..." stuff, which doesn't like __extension__ in front of that, it seems. In addition g_assert macro is already wrapped around G_STMT_START and G_STMT_END, which is supposed to already take care of adding __extension__ on system and toolchain where that is appropriate. I believe just removing that STFU in front of g_assert on that line would fix that particular build failure. Reassigning to xscreensaver maintainers, as I'm sure it's a xscreensaver bug (rather than gtk+ or something else)
Upstream: <snip snip> I suppose taking out that one STFU is the right fix, though I'm told that __extension__ no longer quiets the warning about string length, which means there will now be spurious warnings all over xscreensaver's build log, and I have no idea how to fix that. </snip snip>
Thanks, should be fixed in 5.04-r1.
