- * PDCLib does not attempt or claim POSIX comformance, but makes available these

- *   (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++.
