Just to resume, here's the error:

Searching the web I've found a similar issue: 
http://support.microsoft.com/kb/148652/en-us
however I couldn't fix my problem yet.
 From what I see, one possible solution would be to link LIBCPMT.LIB and 
LIBCMT.LIB before the other libraries.

On the other hand compiling the external as a shared library it works:

    link /DLL  /nologo /INCREMENTAL:NO  /LIBPATH:"C:\_pd_"\bin /LIBPATH:"C:\
    _pd_"\bin /LIBPATH:"C:\_pd_"\flext test_ChambFilter~.obj 
    fftoourad.obj fftooura
    f.obj  BlkDsp.obj AudioSynth.obj  SpecMath.obj  pthreadVC.lib pd.lib
    LIBCMT.LIB
    LIBCPMT.LIB flext-pd.lib /out:icst_chambfilt~.dll
        Creating library icst_chambfilt~.lib and object icst_chambfilt~.exp

What do you think?

Best,
S
