Pre-process for MPI compilation

Pre-process for MPI compilation

You may need a pre-process before compiling MPI codes. In case of FVCOM2.6.1, the process will be something like below:
[cc]
$cd ~/FVCOM2.6.1/FVCOM_source$ rm mpif.h # Remove if it exists.
$rm makedepends # Remove if it exists.$ touch makedepends
$ make depend # Requires makedependf90
[/cc]

Then, you can make as usual.
