(Makefile.am): Substitute GNULIB_WAITPID. * modules/waitpid (configure.ac): Invoke gl_SYS_WAIT_MODULE_INDICATOR. * tests/test-sys_wait-c++.cc (GNULIB_NAMESPACE::waitpid): Check the signature only if the 'waitpid' module is present. * doc/posix-functions/waitpid.texi: Mention the 'waitpid' module. * NEWS: Mention the change. * modules/grantpt (Depends-on): Add waitpid. * modules/wait-process (Depends-on): Likewise.
