After I write the message, I read in
   http://gcc.gnu.org/install/specific.html#hppa*-hp-hpux11
that
"
hppa*-hp-hpux11
...
Thread support is not currently implemented, so --enable-threads does not work.
See:

    * http://gcc.gnu.org/ml/gcc-prs/2002-01/msg00551.html
    * http://gcc.gnu.org/ml/gcc-bugs/2002-01/msg00663.html 
"

But I have run tests (not the ones that comes with boost).
We haven't deploy any program with boost 1.30.2 yet, but they seems to work until now (in testing phase). Perhaps we are not making good tests. ;)

I will try to execute all the boost test programs but perhaps you know which are the ones that demostrates that "GNU C on HP-UX does not support threads" ;).
¿Is there some concrete feature that doesn't work?

Uhhmmm. I thought that they have built gcc with --enable-threads, but it seems impossible. I have to check it out.

So, after all, it seems that, again, you are right. 8)

Thanks a lot, and, please, excuse my poor English.
