[Pw_forum] Make file for JS20 power pc

[Ari P Seitsonen]

Dear Mousumi,

   The problem is the "strange" mixture of AIX vs linux options. 
Specifically, the xlf* compilers should NOT get the '-D...' options on the 
command line at all (because they are processed with the 'cpp' already). 
OR, you tell the 'configure' that it should process the *.f90 files 
directly (thus avoiding 'cpp'), but for this you need to check the 
compiler options for xlf* anyway. The fastest way is probably to take the 
'-D*' options away from the compiler flags (and thus leave them only for 
the pre-processor 'cpp').

   The next problem will probably be, how to compile the parallel version: 
With 'mpxlf*' or with 'mpif90'; that depends on the installation of your 
system, but I guess it will be the second one.

   Good luck!

     Greetings from Paris,
