A new type of compiler warnings had been added recently, this looks like
it.  See 8c9377b6c4e "Try declaring `delq` and `delete`
important-return-value (bug#61730)".

These warn about calls of `delq' and `delete' whose return value is not
used: a common pitfall is to expect that these functions could be used to
modify a sequence in place, which is only correct in few cases.
