Hi, while trying to get Perl-5.8.0-to-be running on NetBSD sparc64,
   we ran into this oddity (this is a severely cut down version of a
   test run by Perl's Configure script):

   [ .. ]
   % uname -a
   NetBSD rfhs8036 1.5ZA NetBSD 1.5ZA (GENERIC) #0: Sun Dec 23 03:12:29 PST 2001     chs@ultra2:/build/obj/build/src/sys/arch/sparc64/compile/GENERIC sparc64


there have been a whole bunch of double floating point fixes made
since this time, if i recall correctly.  i don't have my U5 turned
on currently so i can't check if this test is fixed now, but can
someone with a modern compiler test.  (jmc?)
