* Minor bug fixes from OpenBSD (and some stuff to ease diff'ing in the future)

* Some initial support for FreeBSD-alpha
* Add some optimizations required by g77, which still might be of some use
  to adventuring C/C++ programmers.

+ Perform the optimization of loop unrolling.  This is done for all loops
+ and usually makes programs run more slowly.  @samp{-funroll-all-loops}
+ implies @samp{-fstrength-reduce} as well as @samp{-frerun-cse-after-loop}.
++
++@item -fmove-all-movables
++Forces all invariant computations in loops to be moved
++outside the loop.
++This option is provided primarily to improve performance
++for some Fortran code, though it might improve code written
++in other languages.
++
++@emph{Note:} When compiling programs written in Fortran,
++this option is enabled by default.
++
++Analysis of Fortran code optimization and the resulting
++optimizations triggered by this option, and the
++@samp{-freduce-all-givs} and @samp{-frerun-loop-opt}
++options as well, were
++contributed by Toon Moene (@code{toon@@moene.indiv.nluug.nl}).
++
++Please let us (@code{fortran@@gnu.ai.mit.edu})
++know how use of these options affects
++the performance of your production code.
++We're very interested in code that runs @emph{slower}
++when these options are @emph{enabled}.
++
++@item -freduce-all-givs
++Forces all general-induction variables in loops to be
++strength-reduced.
++This option is provided primarily to improve performance
++for some Fortran code, though it might improve code written
++in other languages.
++
++@emph{Note:} When compiling programs written in Fortran,
++this option is enabled by default.
++
++@item -frerun-loop-opt
++Runs loop optimizations a second time.
++This option is provided primarily to improve performance
++for some Fortran code, though it might improve code written
++in other languages.
++
++@emph{Note:} When compiling programs written in Fortran,
++this option is enabled by default.
+ 
+ @item -fno-peephole
+ Disable any machine-specific peephole optimizations.
