Hi Adam
I have zero idea about this, but can you please specify where (URL) are you getting the source code of clib to have more information about it.
Also, maybe if you specify why are the reassons to compile clib (like for what is required to change the time functions code in your case, or if it just an experiment, or if it just because you want to learn how to compile it ) someone can give you some idea or a workarround.
Regards
