I'd appreciate it if an svn guru could let me know if anything
needs to be done to record the fact that this is a merged copy of
/vendor/NetBSD/softfloat/dist at 230364.  `svn merge --record-only $url'
didn't do anything, I'm guessing because there's no history yet.
The previous libc/softfloat sources were a mishmash, so I didn't try
to recreate any merge history for those.
