>Description:
        devel/glib2 (2.26.0) fails to compile on NetBSD 4.0
        (the previous version, 2.24.2, worked OK).

        I've listed thts as critical/high as half the world depends
        upon glib2, it really needs to build...

>How-To-Repeat:
        I use pkg_comp with NetBSD 4.0 release sets installed (and libkver)
        to simulate a pure NetBSD 4.0 environment.

        In that environment, attempting to build devel/glib2
        results in...

>Fix:
        No idea.   I took a look, and don't see much difference between
        the 2.24.2 that builds, and 2.26.0 that doesn't.   In particular,
        the line that is 885 (in 2.26.0) looks unchanged - so the syntax
        error must be inherited from some include file that's changed.

        As best I can see, on NetBSD 4.0, no built-in atomic ops are
        supported (in particular, G_ATOMIC_I486 is not defined - this
        is a PC class system, 32 bits) and configure determines that it
        can't use assembler for atomic operations ...

conftest.c:(.text+0x1b): undefined reference to `__sync_bool_compare_and_swap_4'

        and (of course) we have no futex() sys call.
