     30  * __xpg6 (C99/SUSv3) was first introduced in Solaris 10.
     31  *
     32  * This is the default value that is compiled into libc.
     33  *
     34  * The default setting, _C99SUSv3_mode_OFF, means to retain current
     35  * Solaris behavior which is NOT C99 and SUSv3 compliant.
     36  * This is normal.  libc determines which standard to use based on
     37  * how applications are compiled.  libc at runtime determines which
     38  * behavior to choose based on the value of __xpg6.
     39  * But by default libc retains its original Solaris behavior.
     40  *
     41  * __xpg6 is used to control certain behaviors between the C99 standard,
     42  * the SUSv3 standard, and Solaris.  More explanation in inc/xpg6.h.
     43  * The XPG6 C compiler utility (c99) will add an object file that contains an
     44  * alternate definition for __xpg6.  The symbol interposition provided
     45  * by the linker will allow libc to find that symbol instead.
     46  *
     47  * Possible settings are available and documented in inc/xpg6.h.
