[Bug fortran/30107] New: improve diagnostic of RECURSIVE LOGICAL SUBROUTINE

["dfranke at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The diagnostic of the code below is rather "generic". A more verbose message
would be preferable. Without RECURSIVE, gfortran gives "Error: Syntax error in
data declaration".

$> cat foo.f90
RECURSIVE LOGICAL SUBROUTINE foo()
END SUBROUTINE

$> gfortran-svn -c -Wall -g foo.f90
foo.f90:1:

RECURSIVE LOGICAL SUBROUTINE foo()
1
Error: Unclassifiable statement at (1)

$> gfortran-svn -v
gcc version 4.3.0 20061206 (experimental)
