Ehhh... I think this may be nit-picking, but its probably right.

Alright. How about THESE macros:

# Disttag macros (you really only want to use %{disttag})
# When we get to Fedora Core 6, we'll need to revisit this.

%disttaglong %{expand:%%(rpm -q --whatprovides redhat-release --qf
'%{VERSION}')}
%rheldisttag %{expand:%%(echo %{disttaglong} | sed -e 's/[^0-9.]//g' -e
's/^/el/')}
%rhldisttag  %{expand:%%(echo %{disttaglong} | cut -d "." -f 1 | sed -e
's/^/rh/')}
%fcdisttag   %{expand:%%(echo %{disttaglong} | sed -e 's/^/fc/')}
%disttag     %{expand:%%(if echo %{disttaglong} | grep "[^0-9.]"
> /dev/null; then \
  case "%{rheldisttag}" in \
    ( "el2" ) \
    echo 0.%{rheldisttag} \
    ;; \
    ( "el3" ) \
    echo 1.%{rheldisttag} \
    ;; \
    ( "el4" ) \
    echo 2.%{rheldisttag} \
    ;; \
    ( "el5" ) \
    echo 3.%{rheldisttag} \
    ;; \
  esac; \
else \
  case "%{disttaglong}" in \
    ( "7.0" | "7.1" | "7.2" | "7.3" | "8" | "9" ) \
    echo 0.%{rhldisttag} \
    ;; \
    ( "1" | "2" | "3" ) \
    echo 1.%{fcdisttag} \
    ;; \
    ("4" | "5" | "6" ) \
    echo 2.%{fcdisttag} \
    ;; \
  esac; \
fi;)}
