| Dear Sirs,
| I need help for a problem that seems very hard to solve for me but
| probably it's a very naive question for developers of gcc.
| I need a way to get a unique  integer value for any (pre-defined
| or user defined) type i.e., I need some function (let's call it
| c_type()) that outputs an integer type descriptor for any variable
| or expression.

It is not documented, but you can use the __builtin_classify_type
function, which will return an integer based on the type of the
argument.  The include file typeclass.h in the compiler release
directory (& included below), give the values returned:

	/* Values returned by __builtin_classify_type.  */

	enum type_class
	{
	  no_type_class = -1,
	  void_type_class, integer_type_class, char_type_class,
	  enumeral_type_class, boolean_type_class,
	  pointer_type_class, reference_type_class, offset_type_class,
	  real_type_class, complex_type_class,
	  function_type_class, method_type_class,
	  record_type_class, union_type_class,
	  array_type_class, string_type_class, set_type_class, file_type_class,
	  lang_type_class
	};

Note that all structures return the same value, as do functions, etc.

You are in a twisty little passage of standards, all conflicting.
