I don't think that's quite right, either.  You want this to be enabled=20=

if e.g. -mcpu=3D403, right? :-)

Maybe something like:

#define CC1_SPEC \
"-mno-multiple \
  %{mstrict-align: -mstrict-align} \
  %{mno-strict-align: -mno-strict-align} \
  %{!mstrict-align: \
    %{!mno-strict-align: \
      %{!mcpu=3D60*: \
        %{!mcpu=3D74*: \
          %{!mcpu=3D75*: -mstrict-align}}}}}"

(I think I got the logic right there :-)

Also note that this should be done in the NetBSD-specific rs6000 config=20=

file, not in the generic rs6000.h.
