They didn't pass - I've got the compiler output somewhere and will try 
to email them to the list in a separate mail, unless it is preferred if 
I stick it on some web space. It's fairly small (about 20k compressed). 
The error message are rather weird and need further investigation.

I've managed to come to an arrangement with my manager that will allow 
me to use my work computer in my spare time to look into these problems 
and hopefully be able to track down the issues and submit fixes.

It's actually not "patchworthy" at the moment, but the secret to success 
in this case is that you need to specify the following options:

-features=tmplife      This instructs the compiler to use standard C++ 
lifetime/scoping rules for temporaries. By default, it's backward 
compatible with old SUN compilers that implemented different rules and 
this breaks the boost smart_ptr tests. This is the only compiler flag 
you need to set on the SUNPRO 5.5 compiler.

-instances=static      The smart pointer templates and the SUN template 
cache database of the older compilers don't agree, which is why you're 
getting link failures when trying to link anything that uses them. This 
switch sticks all the static variables into the object file itself (it 
basically disables the template cache). Results are bigger object files, 
but together with the switch above this makes the smart pointer library 
work on the 5.3 compiler also.

On Solaris 2.6 I also had to edit the jamfile to link it libposix4 for 
the real time functions, otherwise the tests themselves won't link. May 
be different on newer versions - I didn't have the time to verify that.
