/* 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. */
