gcc/fortran
	PR fortran/102241
	* gfortran.h: Add symbol attribute 'pdt_comp'.
	* module.cc : Add 'pdt_comp' to 'ab_attribute' and 'attr_bits'.
	(mio_symbol_attribute): Set 'pdt_comp'.
	* resolve.cc (resolve_component): If a PDT component is found
	in a non-PDT type, generate the PDT instance, if necessary, and
	set the 'pdt_comp' attribute. Fix some whitespace issues.
	* trans-decl.cc (gfc_get_symbol_decl, gfc_trans_deferred_vars):
	If 'pdt_comp' set, initialize the PDT components.
	* trans-stmt.cc (gfc_trans_deallocate): Verify that a typespec
	parameter list is available for PDT components of ordinary
	derived types.
