  38  * Define some feature test macros to make sure that everything we want
  39  * to be declared gets declared.
  40  *
  41  * On some UN*Xes we need to force strtok_r() to be declared.
  42  * We do *NOT* want to define _POSIX_C_SOURCE, as that tends
  43  * to make non-POSIX APIs that we use unavailable.
  44  * XXX - is there no portable way to say "please pollute the
  45  * namespace to the maximum extent possible"?
  46  *
  47  * We also want to force crypt() to be declared on systems that use
  48  * GNU libc, such as most Linux distributions.
