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.
