[CIG-SEISMO] [mpich-discuss] MPICH mpif.h incompatible with gfortran-4.8 -std=f2003

[Dimitri Komatitsch]

Dear all,

The (only) three things to do to make mpif.h conform to recent standards 
(F90, F95, F2003) would be:

- change all character* declarations to character(len=...)

- change all real*8 to either double precision or real(kind=8)  (both 
are OK)

- change all integer*8 to integer(kind=8)


The reason is that F90 considers F77-style declarations 
"type_of_the_variable*" as obsolescent and outputs a warning, and F95 
and later consider that as obsolete and refuse to compile.

Thanks,
Dimitri.
