gcc-4.5.0-1:  upstream update  add new deps (libmpc, libelf)  enable link time optimization  tidy up configure  add c89 and c99 launcher scripts (POSIX compatibility)

Will we at some point want to add the -lto flag (or whatever it is) to both CFLAGS and LDFLAGS in our defaults?

It is -flto  (and if you are really keen, add -fwhopr  with -fwhole-program - experimental).

I would not advocate adding it by default.  Linking is a lot slower (obviously) and it seems to use more memory...  sometimes a lot more. OK sounds good.

I'd let the ricers play with this flag for a while before considering it as the default. But they get to have all the fun! :P http://www.pbase.com/ha3349/image/76708585
