Yes, it's because <sys/types.h> defines it.  I changed ntp.h like this
to make it compile on Ultrix RISC v4.1:

*** ntp.h.orig	Thu Oct 26 14:17:36 1989
--- ntp.h	Thu May 16 15:59:08 1991
***************
*** 7,17 ****
--- 7,19 ----
   * use it.  On machines where signed char doesn't work, char had better
   * be signed.
   */
+ #if !defined(ultrix)
  #if defined(NO_SIGNED_CHAR_DECL)
  typedef char s_char;
  #else
  typedef signed char s_char;
  #endif
+ #endif /* ultrix and mips */
  
  /*
   * NTP protocol parameters.  See section 3.2.6 of the specification.
