[Bug fortran/23994] New: PROTECTED attribute (F2003) is not implemented

[fxcoudert at gcc dot gnu dot org]

Fortran 2003 defines the PROTECTED attribute for variables in modules. Example:

-----------------------------------
MODULE temperature
 REAL,PROTECTED :: temp
 CONTAINS
 SUBROUTINE set_temperature
   temp = 0.0
 END SUBROUTINE
END MODULE

use temperature
call set_temperature
print *, temp
temp = 42
end
-----------------------------------

The compiler should issue an error message on that code (temp cannot be modified
from outside the module) but the code should compile fine without the "temp =
42" line.

The only compiler I know that behaves correctly right now is IBM's.
