Why warning on configure --enable-openmp ?

[schloegl]

I'm trying to use OpenMP within some mex-files, When configuring octave
with openmp enabled,
   ./configure --enable-openmp
one gets the following warning:

configure: WARNING: You used the EXPERIMENTAL --enable-openmp option.
configure: WARNING: Are you sure that is what you want to do?
configure: WARNING:
configure: WARNING: This option enables experimental SMP multithreding
configure: WARNING: code that has had very little testing. There is no
configure: WARNING: certainity that the results returned by Octave with
configure: WARNING: this option enabled will be correct.

However, there is no single
        #pragma omp
within the whole source code of octave - OpenMP is obviously not used by
the core of Octave. Therefore, I'm wondering what this warning is about?
Should this warn about the possibility that some library might give wrong
results? What is the problem the warning tries to warn about ?
