 The !SciPy Windows build with Intel Visual Fortran fails when linking
 fftpack. Build logs for !NumPy and !SciPy are attached.

 site.cfg contains:
 {{{
 [mkl]
 include_dirs = C:\Program Files\Intel\MKL\9.1\include
 library_dirs = C:\Program Files\Intel\MKL\9.1\ia32\lib
 mkl_libs = mkl_c_dll, libguide40
 lapack_libs = mkl_lapack
 }}}

 Build command:
 {{{
 python setup.py -v config --compiler=msvc --fcompiler=intelv build_clib
 --compiler=msvc --fcompiler=intelv build_ext --compiler=msvc
 --fcompiler=intelv install
 }}}

 Build error:

 {{{
 drfft.obj : error LNK2019: unresolved external symbol _dfftb_ referenced
 in function _drfft_fftpack
 drfft.obj : error LNK2019: unresolved external symbol _dfftf_ referenced
 in function _drfft_fftpack
 drfft.obj : error LNK2019: unresolved external symbol _dffti_ referenced
 in function _get_cache_id_drfftpack
 build\lib.win32-2.5\scipy\fftpack\_fftpack.pyd : fatal error LNK1120: 3
 unresolved externals
 }}}

 I'm guessing something is going wrong somewhere with how the symbol names
 are mangled.
