Ada does this using a pragma Import (StdCall ...)  mechanism
See ada/decl.c (in particular the huge function gnat_to_gnu_entity where
it says
	if (Has_Stdcall_Convention (gnat_entity))
	  prepend_one_attribute_to
	    (&attr_list, ATTR_MACHINE_ATTRIBUTE,
	     get_identifier ("stdcall"), NULL_TREE,
	     gnat_entity);
