Fix psignal, psiginfo declaration conditions (bug 18483).
signal.h declares psignal and psiginfo if __USE_XOPEN2K - that is, for the 2001 edition of POSIX. These functions were actually added in the 2008 edition (as indicated in the header comments). This patch fixes the header conditionals. This fixes some linknamespace test failures because psiginfo uses fmemopen, which is also new in the 2008 edition, so before the header fix this appeared to the linknamespace tests as a 2001 function bringing in references to a 2008 function. The problem also appeared in conformtest header namespace test results (the conformtest data has correct conditionals for when these functions should be visible), but the affected headers still have other namespace problems so this doesn't fix any of those XFAILs. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). [BZ #18483] * signal/signal.h [__USE_XOPEN2K] (psignal): Change condition to [__USE_XOPEN2K8]. Remove redundant #endif. [__USE_XOPEN2K] (psiginfo): Change condition to [__USE_XOPEN2K8]. Remove redundant #if. * conform/Makefile (test-xfail-XOPEN2K/signal.h/linknamespace): Remove variable. (test-xfail-XOPEN2K/sys/wait.h/linknamespace): Likewise. (test-xfail-XOPEN2K/ucontext.h/linknamespace): Likewise.
