Hi everybody,
it seems like gcc/g++ continues to generate bogus warnings at a
rate that makes it difficult to
keep up with. For that reason I have written a README-11-bogus-compiler-warnings
which
explains how to deal with this. SVN 1276.
Maybe somebody would like to report this as a compiler error.
Strictly speaking it is not
because the warning itself says "maybe", but IMHO it should not
occur under -Wall
but only under -Wextra.
Best Regards,
Jürgen
