168 * All of the feature test macros come in the following forms
169 * _PDCLIB_*_MIN(min): Available in versions > min
170 * _PDCLIB_*_MINMAX(min, max): Available in versions > min < max
171 * _PDCLIB_*_MAX(max): Availabel in versions < max
173 * The defined tests are:
174 * C: C standard versions
175 * 1990, 1995, 1999, 2011
176 * CXX: C++ standard versions
178 * POSIX: POSIX extension versions.
179 * 1 (POSIX.2), 2 (POSIX.2), 199309L (POSIX.1b),
180 * 199506L (POSIX.1c), 200112L (2001), 200809L (2008)
181 * XOPEN: X/Open System Interface (XSI)/Single Unix Specification
182 * 0 (XPG4), 500 (SUSv2/UNIX98), 600 (SUSv3/UNIX03), 700 (SUSv4)
184 * PDCLib does not attempt or claim POSIX comformance, but makes available these
