[Spglib-users] spglib_f08.f90 fails to compile with gfortran earlier than 4.7

[Keith R. <kr...@gm...>]

I found that the Fortran interface spglib_f08.f90 fails to compile using 
gfortran 4.6.x or earlier.

Source/Utility/spglib_f08.f90:360.34:

             import SpglibDataset_c
                                   1
Error: Cannot IMPORT 'spglibdataset_c' from host scoping unit at (1) - 
does not exist.

...

This appears to be a bug in the compiler, and later versions work fine. 
  However there is a simple workaround - move the definition of the
SpglibDataset_c type to the top level of the module.  Then it works as 
far back as gfortran 4.3.

I hope this is useful.
