Dear All,

I have had some problems with 
  Cannot export _bss_end__: symbol not defined
messages and friends again for the cvs Numerical Python package.

Although the LAPACK-module uses the DL_EXPORT approach and works fine,
the other packages apparently try the .def-approach (which I barely
heard about); this packages do not build for me on latest Cygwin. (I
have not tried it on older ones.)

Putting DL_EXPORTs around all the init-functions fixes this for me:
