Type ssize_t, off_t not found when including thtk/thtk.h

Hi, I had successfully built and installed the library only Debian 13 machine, but when trying to include the thtk/thtk.h header I got the following errors:

Of course, including <sys/types.h> works on my end but can you fix this for the library?
Thank you
