To quote the release-notes[1]: > When _DYNAMIC_STACK_SIZE_SOURCE or _GNU_SOURCE are defined, > PTHREAD_STACK_MIN is no longer constant and is redefined to > sysconf(_SC_THREAD_STACK_MIN). This supports dynamic sized register > sets for modern architectural features like Arm SVE. This basically means that if the above applies, `#if PTHREAD_STACK_MIN > 0` won't compile anymore because `PTHREAD_STACK_MIN` isn't a hard-coded number, but `__sysconf (__SC_THREAD_STACK_MIN_VALUE)`[2]. The issue (for 1.69, 1.70, 1.72 - the other versions seem OK) was reported upstream, but only for Solaris[3], however the corresponding patches[4] seem to work as well for us.
