All I know is that feature test macros have been cleaned up in 2.19, so
perhaps it led to a change in behavior.

In general, using -Werror is very risky, because a slight change in a
third-party header, or in compiler warnings, can cause the project to
fail to build.  In Guile building with -Werror is opt-in for this
reason.
