With -fimplicit-none, this simple module produces an ICE, instead of an
"variable not defined" error message:
[olchansk@dork user]$ more test_namelist.f90
module test_namelist
  integer foo
  !integer bar
  namelist /nlBar/ foo, bar
end module test_namelist
[olchansk@dork user]$
/triumfcs/trshare/olchansk/gcc-tree-ssa/install-20030806/bin/gfortran -c
test_namelist.f90 -fimplicit-none
test_namelist.f90:0: internal compiler error: in gfc_typenode_for_spec, at
fortran/trans-types.c:307
