Only declare __sigpause in installed signal.h when necessary.
This patch makes the installed signal.h declare __sigpause only when
necessary (when a macro definition of sigpause makes use of
__sigpause), rather than unconditionally. This fixes false positives
in the linknamespace tests by making it visible to those tests that no
use of ISO C functionality will actually bring in the definition of
__sigpause and so bring in the other symbols defined in the same
object. There is no bug filed in Bugzilla because this is fixing
false positives rather than any user-visible bug.
Tested for x86_64 (testsuite, and that installed stripped shared
libraries are unchanged by this patch).
* signal/signal.h (__sigpause): Only declare if [__USE_XOPEN &&
!__GNUC__].
* include/signal.h (__sigpause): Move declaration above call to
libc_hidden_proto.
* conform/Makefile (test-xfail-ISO/signal.h/linknamespace): Remove
variable.
(test-xfail-ISO99/signal.h/linknamespace): Likewise.
(test-xfail-ISO11/signal.h/linknamespace): Likewise.
