[Bug fortran/29634] ICE in variable_decl, for function returning a derived type

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

For your initial testcase, Lahey talks about

Compiling program unit main at line 1:
 Interface body name(fun)
  1173-S: "SOURCE.F90", line 6: Derived type definition for 'foo' missing.
 Internal subprogram name()
  2007-W: "SOURCE.F90", line 12: No value assigned to function, entry, or
function result name of function subprogram.
  1712-S: "SOURCE.F90", line 12, column 22: 'fun' already used as an external
function name.
  1069-S: "SOURCE.F90", line 13, column 16: Name 'ieee_class_r4' specified in
END FUNCTION statement must be identical to function name specified in FUNCTION
statement.
Encountered 3 errors, 1 warning, 0 informations in file SOURCE.F90.
Compiling file SOURCE.F90.


With the proposed fix (the hunk against decl.c, the rest seems to be already
fixed on trunk) from Paul for PR 29539, we have

$ gfortran-4.3-HEAD -W -Wall -Wextra -c -o pr29634.o pr29634.f90
 In file pr29634.f90:12

  type(foo) function fun()
                   1
Error: Syntax error in data declaration at (1)
 In file pr29634.f90:13

  end function ieee_class_r4
    1
Error: Expecting END PROGRAM statement at (1)


Which doesn't sound optimal to me.
