More explanation in inc/xpg6.h. 43*0Sstevel@tonic-gate * The XPG6 C compiler utility (c99) will add an object file that contains an 44*0Sstevel@tonic-gate * alternate definition for __xpg6. The symbol interposition provided 45*0Sstevel@tonic-gate * by the linker will allow libc to find that symbol instead. 46*0Sstevel@tonic-gate * 47*0Sstevel@tonic-gate * Possible settings are available and documented in inc/xpg6.h. 48*0Sstevel@tonic-gate */ 49*0Sstevel@tonic-gate 50*0Sstevel@tonic-gate #include "xpg6.h" 51*0Sstevel@tonic-gate 52*0Sstevel@tonic-gate unsigned int __xpg6 = _C99SUSv3_mode_OFF; 53
