* Use of _XOPEN_SOURCE
*
* The following X/Open specifications are supported:
*
* X/Open Portability Guide, Issue 3 (XPG3)
* X/Open CAE Specification, Issue 4 (XPG4)
* X/Open CAE Specification, Issue 4, Version 2 (XPG4v2)
* X/Open CAE Specification, Issue 5 (XPG5)
* Open Group Technical Standard, Issue 6 (XPG6), also referred to as
* IEEE Std. 1003.1-2001 and ISO/IEC 9945:2002.
*
* XPG4v2 is also referred to as UNIX 95 (SUS or SUSv1).
* XPG5 is also referred to as UNIX 98 or the Single Unix Specification,
* Version 2 (SUSv2)
* XPG6 is the result of a merge of the X/Open and POSIX specifications
* and as such is also referred to as IEEE Std. 1003.1-2001 in
* addition to UNIX 03 and SUSv3.
*
* When writing a conforming X/Open application, as per the specification
* requirements, the appropriate feature test macros must be defined at
* compile time. These are as follows. For more info, see standards(5).
*
* Feature Test Macro Specification
* ------------------------------------------------ -------------
* _XOPEN_SOURCE XPG3
* _XOPEN_SOURCE && _XOPEN_VERSION = 4 XPG4
* _XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED = 1 XPG4v2
* _XOPEN_SOURCE = 500 XPG5
* _XOPEN_SOURCE = 600 (or POSIX_C_SOURCE=200112L) XPG6
*
* In order to simplify the guards within the headers, the following
* implementation private test macros have been created. Applications
* must NOT use these private test macros as unexpected results will
* occur.
*
* Note that in general, the use of these private macros is cumulative.
* For example, the use of _XPG3 with no other restrictions on the X/Open
* namespace will make the symbols visible for XPG3 through XPG6
* compilation environments. The use of _XPG4_2 with no other X/Open
* namespace restrictions indicates that the symbols were introduced in
* XPG4v2 and are therefore visible for XPG4v2 through XPG6 compilation
* environments, but not for XPG3 or XPG4 compilation environments.
*
* _XPG3 X/Open Portability Guide, Issue 3 (XPG3)
* _XPG4 X/Open CAE Specification, Issue 4 (XPG4)
* _XPG4_2 X/Open CAE Specification, Issue 4, Version 2 (XPG4v2/UNIX
95/SUS)
