I would feel better if you escaped the loop when you found *.o or *.obj, so
no other yet unknown extension later in the alphabet will override it...

How about doing something along the same lines for exeext:

  for ac_file in `ls conftest.exe conftest conftest.* 2>/dev/null`; do
    case $ac_file in
      conftest )            ac_cv_exeext=;;
      *.$ac_cv_object ... ) ;;
      *)                    ac_cv_exeext=`expr "$ac_file" : '.*\.\(.*\)'`;;
    esac
  done

The problem is, we would probably have to change the ls line for each new exeext
anyways, as the address@hidden@ environment would try to magically hide it and 
you would
hit with plain `conftest'...
