* This is the default value that is compiled into libc.
*
* The default setting, _C99SUSv3_mode_OFF, means to retain current
* Solaris behavior which is NOT C99 and SUSv3 compliant.
* This is normal. libc determines which standard to use based on
* how applications are compiled. libc at runtime determines which
* behavior to choose based on the value of __xpg6.
* But by default libc retains its original Solaris behavior.
*
* __xpg6 is used to control certain behaviors between the C99 standard,
* The XPG6 C compiler utility (c99) will add an object file that contains an
* alternate definition for __xpg6. The symbol interposition provided
* by the linker will allow libc to find that symbol instead.
