compilation error with CVS 2006-Nov-01 10:05 MET

[Werner LEMBERG]

I get this strange warning which consequently leads to an error:

  rm -f ./out/parser.dep;
  DEPENDENCIES_OUTPUT="./out/parser.dep ./out/parser.o" \
  g++ -c -Woverloaded-virtual \
         -DHAVE_CONFIG_H -DNDEBUG \

  make[1]: *** [out/parser.o] Error 1
  make[1]: Leaving directory `/home/wl/cvs/lilypond.compiled/lily'

Why do we have -Werror?

This is g++ (GCC) 4.0.2 20050901 (prerelease) on a GNU/Linux box; I've
just called autogen.sh, using autoconf 2.60a.
