-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.
