Merge #18887: build: enable -Werror=gnu
a30b0a24e97eae7f6d1428c5bf339a579872f28e build: enable -Werror=gnu (Vasil Dimov)
Pull request description:
Stop the build if a warning is emitted due to `-Wgnu` and
`--enable-werror` has been used. As usual - this would help notice such
a warning that is about to be introduced in new code.
This is a followup to
https://github.com/bitcoin/bitcoin/pull/18088 build: ensure we aren't using GNU extensions
