- * PDCLib does not attempt or claim POSIX comformance, but makes available these
- * extensions as
- * (a) useful, and
- * (b)
+ * Additionally, the macros
+ * _BSD_SOURCE, _SVID_SOURCE and _GNU_SOURCE
+ * are adhered to. If _GNU_SOURCE is defined, _XOPEN_SOURCE and
+ * _POSIX_C_SOURCE are defined to their most recent values to match glibc
+ * behaviour
+ *
+ * The intention of supporting these feature test macros is to ease
+ * application portability from these systems to PDCLib systems; in addition,
+ * it eases support for these standards by systems supporting them which are
+ * using PDCLib as their default C library.
+ *
+ * Applications targetting purely PDClib/PDCLib based platforms may define
+ * just _PDCLIB_EXTENSIONS, which will enable all supported extensions, plus
+ * all features from all supported versions of C and C++.
