 # CHANGES:
-#	+ Remove xxx_TCL_DECLARED #ifdeffery
-#	+ Use application-defined storage class specifier instead of "EXTERN"
-#	+ Add "epoch" and "revision" fields to stubs table record
-#	+ Remove dead code related to USE_*_STUB_PROCS (emitStubs, makeStub)
 #	+ Second argument to "declare" is used as a status guard
 #	  instead of a platform guard.
-#	+ Use void (*reserved$i)(void) = 0 instead of void *reserved$i = NULL
-#	  for unused stub entries, in case pointer-to-function and
-#	  pointer-to-object are different sizes.
 #	+ Allow trailing semicolon in function declarations
-#	+ stubs table is const-qualified
