+Subject: [PATCH] libntp: Do not use PTHREAD_STACK_MIN on glibc
+In glibc 2.34+ PTHREAD_STACK_MIN is not a compile-time constant which
+could mean different stack sizes at runtime on different architectures
+and it also causes compile failure. Default glibc thread stack size
+or 64Kb set by ntp should be good in glibc these days.
+Upstream-Status: Pending
