  34  * See /ws/unix200x-gate/usr/src/lib/libc/port/gen/xpg6.c for libc default.
  35  * __xpg6 (C99/SUSv3) is first included in Solaris 10 libc and libm
  36  * as well as the K2 (S1S8) libsunmath and libmopt.
  37  *
  38  * The default setting, _C99SUSv3_mode_OFF, means to retain current Solaris
  39  * behavior which is NOT C99/SUSv3 compliant.  This is normal.  These libraries
  40  * determine which standard to use based on how applications are built.  These
  41  * libraries at runtime determine which behavior to choose based on the value
  42  * of __xpg6.  By default they retain their original Solaris behavior.
  43  *
  44  * __xpg6 is used to control certain behaviors between the C99 standard, the
  45  * SUSv3 standard, and Solaris.  More explanation in lib/libc/inc/xpg6.h.
  46  * The XPG6 C compiler utility (c99) will add an object file that contains
  47  * an alternate definition for __xpg6.  The symbol interposition provided
  48  * by the linker will allow these libraries to find that symbol instead.
  49  *
  50  * Possible settings are available and documented in lib/libc/inc/xpg6.h.
