28  * __xpg6 (C99/SUSv3) was first introduced in Solaris 10.
29  *
30  * This file is NOT linked into libc.  See xpg6.c.
31  * This value is linked into an application when the application is
32  * requesting conforming C99/SUSv3 behavior.  This is usually done
33  * with the c99 utility.
34  *
35  * __xpg6 is used to control certain behaviors between the C99 standard,
36  * the SUSv3 standard, and Solaris.  More explanation in inc/xpg6.h.
37  * The XPG6 C compiler utility (c99) will add an object file that contains an
38  * alternate definition for __xpg6.  The symbol interposition provided
39  * by the linker will allow libc to find that symbol instead.
40  *
41  * Possible settings are available and documented in inc/xpg6.h.
