   + --with-gmp is surplus to requirements, mpeval should always be built --
     either with libgmp if it is available, or else without it.  Whether
     or not to use mpeval is then determined at runtime, if the user tries
     to `load(`mpeval')'.
 
-  + The `shadowed' flag in every symbol is only used by m4_dump_symbol(),
-    and could be determined instead by the presence of an identically

-    doing would slow down dumpdef, but speed up the rest of the symbol
