[Wien] ISO_C_BINDING module

[tasaka at affinity-science.com]

Hello,

I found that version 12.1 requires ISO_C_BINDING module.
this is a Fortran 2003 extension and some f90/f95 compilers don't support it.
For the users who use that compilers, should they choose version 11.1?
if anyone know the workaround, please advise.

With best regards,
Tomo
