Re: [Boost-users] Building and testing smart pointers using HP-UX/G++

When I added -DBOOST_SP_USE_PTHREADS smart_ptr_test ran, like John 
Maddock found already.  I assume the following output is correct:

UDT with value 999888777 being destroyed
UDT with value 111222333 being destroyed
OK
UDT with value 54321 being destroyed
UDT with value 333 being destroyed
UDT with value 222 being destroyed
UDT with value 111 being destroyed
UDT with value 333222111 being destroyed
No errors detected.

For what it's worth, it worked with both -O0 and -O2.

Adding "-D_REENTRANT -pthread " to my original g++ command line, on the 
other hand, did not change the original behavior.

Combining Peter's and Ben's suggested flags works.
