True, I have changed the summary.
The underlying problem I guess then is that packages use -Werror, but this
warning depends on specific settings of the optimizer which changes from user
to user.
But "don't use -Werror" or "don't use CFLAGS" is not a useful solution either.
Clearly many projects are affected by this.
