I want to chase overlapping patterns in a larger code base.
So I use -Werror -Woverlapping-patterns .
But the code also needs -fglasgow-exts
and this makes compilation stop right at the beginning, with
"warning: -fglasgow-exts is deprecated: ..."
which will be turned into an error because of -Werror
-Wno-warnings-deprecations does not help,
apparently that warning is not a deprecation.
Is there a way to get -Werror for specific warnings?
