Looking deeper into this, it looks like the right solution is to use sysconf(_SC_PAGESIZE) instead of getpagesize(). getpagesize() looks deprecated, that's why it's getting disabled when modern features are enabled. I'll send a patch to use sysconf when supported and fallback to the old getpagesize() otherwise. Brice
