I supposed Solaris 2.5.1 (release 1996) is just too old to add

Yeah, its old. Unfortunately for us, we still have to support it.
To set the record straight, the issue is not threads. Threads work fine
on 2.5.1. This is a configure system linking issue, "gethostbyname"
requires linking with libnsl.so. So, thread_test.c must link with -lnsl.
The bigger issue is that the configure script needs to include -lnsl for
older solaris platforms. Solaris 2.5.1 has "gethostbyname_r" but the
configure check fails for the same reason.
configure:19821: checking for gethostbyname_r
configure:19877: gcc -o conftest -O2 -Wall [...snip...]
Undefined first referenced
symbol in file
gethostbyname_r /var/tmp//ccSuGLEn.o (symbol
belongs to implicit dependency /usr/lib/libnsl.so.1)
ld: fatal: Symbol referencing errors. No output written to conftest
collect2: ld returned 1 exit status
This is why thread_test.c thought it had to fall back on gethostbyname
in the first place.
Forgot to mention, there is an easy fix:
~]# LDFLAGS="-lnsl" ./configure --enable-thread-safety
