I've had a try at the new 1.4.1rc2 and my existing binaries that were linked 
with 1.3.0 runs all the tests without difficulty (so ABI compatibility seems 
good), but every time that a Cython extension is loaded, I get the next 
warning:

/home/faltet/PyTables/pytables/trunk/tables/__init__.py:56: RuntimeWarning: 
numpy.dtype size changed, may indicate binary incompatibility
  from tables.utilsExtension import getPyTablesVersion, getHDF5Version
/home/faltet/PyTables/pytables/trunk/tables/file.py:43: RuntimeWarning: 
numpy.dtype size changed, may indicate binary incompatibility
  from tables import hdf5Extension
/home/faltet/PyTables/pytables/trunk/tables/link.py:32: RuntimeWarning: 
numpy.dtype size changed, may indicate binary incompatibility
  from tables import linkExtension
/home/faltet/PyTables/pytables/trunk/tables/table.py:38: RuntimeWarning: 
numpy.dtype size changed, may indicate binary incompatibility

I'm using current stable Cython 12.1.  Is the warning above intended or I'm 
doing something wrong?

Thanks,
