Problem building qt4-libs

["Steve O'Hara-Smith" <steve@xxxxxxxxxx>]

	Hi,

	Building qt4-libs under pkgsrc from the 2010-q1 branch is failing
in
qt-everywhere-opensource-src-4.6.2/src/3rdparty/javascriptcore/JavaScriptCore/runtime/Colletcor.cpp

	... at line 682 where pthread_getattr_np is being called. I don't
understand the thread API will enough to work out how to fix this - The full
block of code involved is:

    static void* stackBase = 0;
    static size_t stackSize = 0;
    static pthread_t stackThread;
    pthread_t thread = pthread_self();
    if (stackBase == 0 || thread != stackThread) {
        pthread_attr_t sattr;
        pthread_attr_init(&sattr);
#if HAVE(PTHREAD_NP_H) || PLATFORM(NETBSD)
        // e.g. on FreeBSD 5.4, neundorf@kde.org
        pthread_attr_get_np(thread, &sattr);
#else
        // FIXME: this function is non-portable; other POSIX systems may
have di fferent np alternatives
        pthread_getattr_np(thread, &sattr);
#endif
        int rc = pthread_attr_getstack(&sattr, &stackBase, &stackSize);
        (void)rc; // FIXME: Deal with error code somehow? Seems fatal.
        ASSERT(stackBase);
        pthread_attr_destroy(&sattr);
        stackThread = thread;
    }
    return static_cast<char*>(stackBase) + stackSize;
