+Subject: [PATCH] Fix build with werror on glibc 2.43.
+
+We've been defining `_XOPEN_SOURCE` and `_POSIX_C_SOURCE` to the same
+values as defined in glibc prior to 2.43. But in 2.43, glibc changes
+them to new values, which means we get a warning when redefining them.
+By `#undef`ing them first, we no longer get a warning.
+
+Closes #27076.
