 The name of that function scares me.
 Seems that it comes from libgcc and it says
 /* WARNING: The code is this function depends on internal and undocumented
    details of the GNU linker and dynamic loader as implemented for parisc
    linux.  */

 and sure enough, this is comparing function pointers.
 I don't know enough about pa-risc to have any idea what it's about,
 but probably something our dynamic linker's doing doesn't match the
 expectations of the libgcc code.
