+   most of the compiler.  This allows header files to use these types
+   (e.g. in function prototypes) without concern for whether the full
+   definitions are visible.  Some other declarations that need to be
+   universally visible are here, too.
+
+   In the context of tconfig.h, most of these have special definitions
+   which prevent them from being used except in further type
+   declarations.  This is a kludge; the right thing is to avoid
+   including the "tm.h" header set in the context of tconfig.h, but
+   we're not there yet.  */
