hi there,
i had problems compiling the latest svn tree.
bootstrapping and configuring worked well.

but after "make" gcc told me that "tune" was an invalid option.

i consulted "man gcc" and found that  -mtune is  not valid for  x86 
target (gcc 3.2.2).
i surfed to http://gcc.gnu.org and found out that -mtune for x86 is only 
valid since gcc 3.4.4.

as -mtune and -mcpu are target machine *and* compiler dependent,
the compiler version should also be used for the decision which flags to 
tune with.
