Thanks, I will use --with-gnumake from now on.

This time I've built everything from scratch,
and Teuchos_MPIReductionOpBase.o
was built without problem. I don't know
what was wrong, and I can only apologize
for the wrong report.

As a side note, after configuring with

../configure  \
--enable-mpi \
--with-mpi-compilers \
--enable-teuchos \
--enable-teuchos-extended \
--enable-teuchos-complex \
--enable-teuchos-expat \
--enable-thyra \
--enable-epetra \
--enable-epetraext \
--enable-amesos \
--enable-amesos-umfpack \
--enable-amesos-thyra \
--enable-ifpack \
--enable-aztecoo \
--enable-ml \
--enable-triutils \
--enable-python \
--with-trilinos \
--enable-nox \
--enable-nox-epetra \
--enable-nox-lapack \
--enable-new_package \
--enable-pytrilinos \
--prefix=/home/marco/local/trilinos-6.0.14 \
--enable-expat

in a clean tree the compilation stopped 5
times, and each error was solved by applying
one of pieces of the  patch sent in my previous post.
If you need the logs,
I can send them to you or to the mailing list
(the .tgz file with make logs is 379066 bytes long),
or I can put them on a web server.

A second note:
I see that some files are compiled with -fno-strict-aliasing
However, I also see a lot of aliasing warning in

plus some ml/examples/Other files
Is it safe to ignore them?

Thanks again,

Marco
