+ * __xpg6 (C99/SUSv3) was first introduced in Solaris 10.
+ *
+ * C99/SUSv3 behavior control bits for __xpg6 variable defined
+ * in port/gen/xpg6.c.
+ * Use these with extreme care.
+ *
+ * Please follow these basic rules for using these bits and
+ * don't convolute their meaning.
+ *
+ * The basic idea here is the upper 16 bits (default_off)
+ * enable/disable existing Solaris behaviors that conflict with
+ * the C99 or SUSv3 standards.  When these bits are on you
+ * are restoring an existing Solaris behavior and no longer
+ * in strict C99/SUSv3 conformance mode.
+ *
+ * The lower 16 bits (default_on) are C99/SUSv3 behaviors
+ * which are strictly conforming behaviors as far as the
+ * C99/SUSv3 standards are concerned.  When these bits are on
+ * you are in C99/SUSv3 conforming mode.  When these bits are off
+ * you have turned off C99/SUSv3 conforming mode and are using
+ * previous Solaris behavior.
+ *
+ * _C99SUSv3_mode_ON and _C99SUSv3_mode_OFF are two meta-definitions
+ * which are the most likely modes to run Solaris in.
+ * However, this frame work allows for other possible behaviors.
+ *
+ * The default mode of libc is _C99SUSv3_mode_OFF.
+ * A C99/SUSv3 conforming application should be compiled
+ * with the XPG6 standards conforming C compiler utility (c99) which
+ * adds an object file that contains an alternate definition
+ * for __xpg6 (_C99SUSv3_mode_ON) thus enabling C99/SUSv3 standards
+ * conforming mode.
