Почему бы не заменить strlen(PRIVATE_PREFIX) на sizeof(PRIVATE_PREFIX)-1 ?
Читабельность кода чуток уменьшится, зато длинна строки оба раза будет
вычисляться при компиляции, а не в run-time.
Это я так, лишь предлагаю.

Кажется gcc умеет оптимизировать strlen для константных строк.

Причем даже с -O0.
