  Modified files:
    lang/gcc45           Makefile 
  Log:
  Add a new option LTO that enables the new link-time optimization framework
  and first optimizations that GCC 4.5 brings.  This adds libelf as a new
  dependency (if used) and is off by default; we may be enabling it at a
  later point, though.
  
  Bumping PORTREVISION since someone who has installed libelf, previously
  to this change would get LTO enabled automatically and then run into
  problems if libelf is removed -- which is possible, since this port
  does not lay down a dependency on that case.

Thanks a lot for the report and including a patch, already.  I made very
minor changes to the patch (swapped to lines in the option handling and
updated the description of LTO) in case you wonder.  That was a good
catch of yours to ensure we don't enable this "by chance" and then run
into problems later.
