Hi Davide!

Yes, something does seem to be wrong with your cpp.  Can you determine
whether its Gnu cpp or a "vendor" cpp?  The "cpp --version" command
might help but I think it only works with Gnu cpp.

OK, this is odd.  I'm curious about the space between the dash and the
capital "P" ("- P") since perhaps that isn't the right syntax.

Please try the following:

  cd MITgcm/verification/exp2
  mkdir build
  cd build
  ../../../tools/genmake2  \
    -of=../../../tools/build_options/osf1_alpha_g77  \
    -mods=../code
  make depend
  make

and the same but with:

  ../../../tools/genmake2  \
    -of=../../../tools/build_options/osf1_alpha_f77  \
    -mods=../code

Will either one work?  If both fail, then it looks like we'll have to
create a custom "optfile" for your system.  The easiest way to do that
is to start with one of the existing optfiles (I'd use "osf1_alpha_g77")
and then modify it.  The first thing I'd try is to change the line that
reads:

  CPP='/usr/bin/cpp -P'

so that it has just:

  CPP='cpp -P'

or

  CPP='cpp'

and see if that helps.  If not, send us an email with the output from
the above sequence and we'll try to hunt down the specific problem.

good luck!
Ed
