As a matter of fact, there are several things in sys/types.h that are not declared if _NO_OLDNAMES is set (including dev_t, ssize_t, pid_t, etc.). I guess that one should never set _NO_OLDNAMES :(
stdlib.h no longer has 'beep' (but it has '_beep')
OK, then please try removing those lines from crtc.c and let me know if everything works.
