[CIG-SEISMO] Some problems with xspecfem3D and the Intel compilers

[Dimitri Komatitsch]

Hi Carène and Fabien, Hi all,

Thanks a lot! Since several users have reported problems with this Intel 
compiler option, in particular with ifort version 17, let me keep it but 
turn it off by default (in 2D, 3D, and 3D_GLOBE).

When it works fine it does speed up I/Os significantly though, thus 
worth trying it. I will mention that in the users manual (of 2D, 3D, and 
3D_GLOBE).

Thanks!
Best regards,
Dimitri.
