Specifically, they’re used to build the macros that make those _thing$UNIX2003 symbols that keep giving people link errors when their SDK settings are wrong. For instance, when targeting 10.5, this declaration from <string.h>:<br />
char *strerror(int) __DARWIN_ALIAS(strerror); expands to:<br />
char *strerror(int) __asm("_strerror$UNIX2003"); As noted in the code, I found out about asm labels in <sys/cdefs.h>. Specifically, they’re used to build the macros that make those _thing$UNIX2003 symbols that keep giving people link errors when their SDK settings are wrong.
