'Minix has include files, but not their libraries?

I'm getting a strange thing using Minix where Minix seems to include some standard UNIX include files, such as <semaphore.h> and <sys/msg.h>, but no man files for them and they don't seem to be in any of the provided libs (there's no libpthread for instance)

Are these just placeholders or am I missing somewhere they're actually provided?
