scipy.sparse does not build on Windows
- with mingw because some of the sources in SuperLU2.0 use sys/times.h, 
  for instance, that is not available on non-posix system like Win32.
  This issue can be fixed by implementing sys/times.h features
  for windows.
- with cygwin because for some reasons _S and _C (if I remember correctly)
  in the definition of Dtype_t enum (in supermatrix.h) are defined
  by compiler and thus causing syntax error. This issue can be fixed by
  renaming Dtype_t items and replacing the corresponding occurrences 
  elsewhere with the new names.
