So the upshot is that that fixed the 8.3 build, but anchovy is still
failing on 8.2, with some different errors:

/usr/bin/ld.gold: /tmp/ccn7RPJJ.ltrans0.ltrans.o: in function base_yyparse:y.tab.c:12777: error: undefined reference to
'filtered_base_yylex'

collect2: ld returned 1 exit status

I went so far as to install Arch Linux here, but I cannot duplicate
the above.  (Although I wonder whether my machine is really doing
link-time optimization, since it doesn't generate any compiler warning
messages during the link step, as anchovy is doing.)

But these errors seem like they should be impossible anyway,
since there is nothing platform-specific about our uses of any of the
mentioned functions.  I wonder if there is something messed up with
anchovy's copy of REL8_2_STABLE.  Marti, could I trouble you to
blow away and recreate that machine's 8.2 checkout, as well as any
compiler cache directories?
