+/* Before including this file, the including file must have included
+   <bits/environments.h> (generally via <unistd.h>) and must have
+   defined the following macros, exactly one of which will be called
+   for each POSIX environment:
+
+   KNOWN_PRESENT_ENVIRONMENT, for POSIX environments that are known to
+   be supported in this libc.
+
+   KNOWN_ABSENT_ENVIRONMENT, for POSIX environments that are known not
+   to be supported on this system.
+
+   UNKNOWN_ENVIRONMENT, for POSIX environments not supported in this
+   libc but possibly supported by another libc on the same system,
+   that can be selected using the same compiler but different
+   compilation options.
+
+   Each macro has arguments (SC_PREFIX, ENV_PREFIX, SUFFIX).  The
+   corresponding argument to sysconf is _SC_##SC_PREFIX##_##SUFFIX.
+   The environment name, as used with getconf, is
+   ENV_PREFIX##_##SUFFIX, and the corresponding macro is the same with
+   a leading "_".
+
+   In addition, the macros START_ENV_GROUP and END_ENV_GROUP must be
+   defined.  These are called with arguments V5, V6, V7 before and
+   after the relevant groups of environments.  */
