 I don't think it's a duplicate of 3314;  unlike 3314 I explicitly 
 specify --enable-threads=posix, and indeed the resulting gcc -v says:
 
 ...
 
 Thread model: posix
 gcc version 3.0.3
 
 
 3314 is about how if you just say --enable-threads
 it may default to no threads.  5383 shows details of how the thread 
 support is bad, when you do get it (by asking explicitly).
 
 Unless you mean, '3314 and 5383 both show that thread support is messed 
 up on hp 11'.  However, I think 5383 has more helpful detail, enough to 
 be worth keeping.  3314 just shows an indirect stumble over the fact 
 that something is wrong.

>Description:
jpararas@tango ~ >gcc -v
Reading specs from /usr/local/gcc303/lib/gcc-lib/hppa2.0w-hp-hpux11.00/3.0.3/specs
Configured with: ../gcc-3.0.3/configure --prefix=/usr/local/gcc303 --with-gnu-as --with-as=/usr/local/bin/as --with-ld=/usr/ccs/bin/ld --enable-threads=posix
Thread model: posix
gcc version 3.0.3


This was compiled with thread support.  However, a simple
Hello World app, Foo.cpp fails to link, as follows:

jpararas@tango ~ >g++ Foo.cpp
/usr/ccs/bin/ld: Unsatisfied symbols:
   pthread_once (code)
   pthread_key_create (code)
   pthread_setspecific (code)
   pthread_mutex_unlock (code)
   pthread_getspecific (code)
   pthread_mutex_lock (code)
collect2: ld returned 1 exit status


And even:

jpararas@tango ~ >g++ -threads Foo.cpp
/usr/ccs/bin/ld: Unsatisfied symbols:
   pthread_key_create (code)
collect2: ld returned 1 exit status

A precompiled, single-thread gcc 3.0.1 (binary from HP)

jpararas@tango ~ >gcc -v
