In most cases you must be careful to match a range of processor types.
For most processor families, a trailing @samp{*} suffices, as in
@samp{mips*} above. For the i386 family, something along the lines of
-@samp{i[3456]86} suffices at present. For the m68k family, you will
+@samp{i[3-7]86} suffices at present. For the m68k family, you will
need something like @samp{m68*}. Of course, if you do not need to match
on the processor, it is simpler to just replace the entire field by a
@samp{*}, as in @samp{*-*-irix*}.
