From my reading, no completed patch was posted in the thread.
AC_REPLACE_FUNCS([getaddrinfo]) will not detect getaddrinfo() on Tru64
UNIX because getaddrinfo is not in libc. Because of this, getaddrinfo
isn't detected and the compilation of src/port/thread.c fails:
cc -std -O2 -ieee -msym -readonly_strings -I../../src/port -DFRONTEND -I../../src/include -I/opt/TWWfsw/gettext014/include -I/opt/TWWfsw/libopenssl097/include -I/opt/TWWfsw/zlib11/include -I/opt/TWWfsw/tcl84/include -I/opt/TWWfsw/tk84/include -pthread --thread-safe -D_REENTRANT -D_THREAD_SAFE -D_POSIX_PTHREAD_SEMANTICS -c thread.c

gmake[2]: *** [thread.o] Error 1

gethostbyname_r() on Tru64 UNIX accepts 3 arguments.
