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