- * NOTE: Do not protect this header against multiple inclusion.  Doing\r

- * and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,\r
- * protect each CPP macro that we want to supply.\r

- * Feature-test macros are defined by several standards, and allow an\r
- * application to specify what symbols they want the system headers to\r
- * expose, and hence what standard they want them to conform to.\r
- * There are two classes of feature-test macros.  The first class\r
- * specify complete standards, and if one of these is defined, header\r
- * files will try to conform to the relevant standard.  They are:\r
- *\r
- * ANSI macros:\r
- * _ANSI_SOURCE                        ANSI C89\r
- *\r
- * POSIX macros:\r
- * _POSIX_SOURCE == 1          IEEE Std 1003.1 (version?)\r
- * _POSIX_C_SOURCE == 1                IEEE Std 1003.1-1990\r
- * _POSIX_C_SOURCE == 2                IEEE Std 1003.2-1992\r
- * _POSIX_C_SOURCE == 199309L  IEEE Std 1003.1b-1993\r
- * _POSIX_C_SOURCE == 199506L  ISO/IEC 9945-1:1996\r
- * _POSIX_C_SOURCE == 200112L  IEEE Std 1003.1-2001\r
- *\r
- * X/Open macros:\r
- * _XOPEN_SOURCE               System Interfaces and Headers, Issue 4, Ver 2\r
- * _XOPEN_SOURCE_EXTENDED == 1 XSH4.2 UNIX extensions\r
- * _XOPEN_SOURCE == 500                System Interfaces and Headers, Issue 5\r
- * _XOPEN_SOURCE == 520                Networking Services (XNS), Issue 5.2\r
- * _XOPEN_SOURCE == 600                IEEE Std 1003.1-2001, XSI option\r
- *\r
- * NetBSD macros:\r
- * _NETBSD_SOURCE == 1         Make all NetBSD features available.\r
- *\r
- * If more than one of these "major" feature-test macros is defined,\r
- * then the set of facilities provided (and namespace used) is the\r
- * union of that specified by the relevant standards, and in case of\r
- * conflict, the earlier standard in the above list has precedence (so\r
- * if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version\r
- * of rename() that's used is the POSIX one).  If none of the "major"\r
- * feature-test macros is defined, _NETBSD_SOURCE is assumed.\r
- *\r
- * There are also "minor" feature-test macros, which enable extra\r
- * functionality in addition to some base standard.  They should be\r
- * defined along with one of the "major" macros.  The "minor" macros\r
- * are:\r
- *\r
- * _REENTRANT\r
- * _ISOC99_SOURCE\r
- * _LARGEFILE_SOURCE           Large File Support\r
- *             <http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>\r
