As shown by conform/ tests once the remaining namespace issues are fixed, the tile bits/sigaction.h fails to declare SA_RESETHAND, SA_RESTART and SA_NODEFER for non-XSI POSIX.1:2008 as other versions do. Those constants were moved from XSI to Base in the 2008 edition of POSIX. This patch fixes the conditions to match other versions of this header. Tested (compilation only) for tilegx-linux-gnu with build-many-glibcs.py. [BZ #21622] * sysdeps/unix/sysv/linux/tile/bits/sigaction.h (SA_RESTART): Define for [__USE_UNIX98 || __USE_XOPEN2K8], not [__USE_UNIX98 || __USE_MISC]. (SA_NODEFER): Likewise. (SA_RESETHAND): Likewise.
