Condition signal.h inclusion in sys/wait.h (bug 21560).
sys/wait.h includes signal.h unconditionally. But the permission to do so is UX-shaded in XPG4.2, and XSI-shaded in POSIX before 2008, so this should not be unconditional. This patch fixes this conservatively: the include is kept, but conditioned on the standards that permit it (meaning it is still present by default, because non-XSI POSIX.1:2008 is enabled by default). <bits/types.h> is now included unconditionally to provide the required definition of __pid_t; it was previously included via <signal.h>. Some standards require pid_t to be defined here, and all allow it to be defined here; previously defined via <signal.h>, it's now defined directly in this header. Tested for x86_64. This does not fix any of the sys/wait.h conformtest failures, but substantially reduces the number of namespace failures for sys/wait.h for XPG4 and POSIX. [BZ #21560] * posix/sys/wait.h: Condition include of <signal.h> on [__USE_XOPEN_EXTENDED || __USE_XOPEN2K8]. Include <bits/types.h> unconditionally. [!__pid_t_defined] (pid_t): Define typedef.
