Noticed this while building a testdir of
$ ./gnulib-tool --create-testdir --dir=/tmp/testdir --single-configure \
--with-c++-tests --avoid=math-c++-tests inet_ntop scandir alphasort \
getaddrinfo vdprintf-posix vfprintf-posix vprintf-posix vsprintf-posix \
connect accept bind getpeername getsockname getsockopt recvfrom sendto \
setsockopt mknod gettimeofday getcwd gethostname getlogin_r read \
sethostname write

pthread-thread: Fix prototype of pthread_attr_getdetachstate.
* lib/pthread.in.h (pthread_attr_getdetachstate): Change first parameter
to 'const pthread_attr_t *'.
* lib/pthread-thread.c (pthread_attr_getdetachstate): Likewise.
* tests/test-pthread-c++.cc (pthread_attr_getdetachstate): Likewise.
