No. POSIX says then they sysconf() return parameter value at _runtime_ and unistd.h have parameter value for _compile time_. It two is completely different styles. Program can do dinamic switch at runtime and static switch at compile time. Currently we have not only _POSIX_SAVED_IDS but _many_ parameters of such kind in unistd.h (duplicated via sysconf), it helps to #ifdef some things at compile time. I know some pgms which use _POSIX_SAVE_IDS for #ifdef and no one which use sysconf(_SC_SAVED_IDS) -- Andrey A.
