...yes, it does (though only because I saw it myself an hour ago, not
because I really know what it means). Anyway, replacing
the offending expressions by ...(len=*)... allows compiling the files with
gfortran(4.1) and final result nearly passes a 'make test.serial' for
amber 9 and therefore presumably for amber8 too.
Buy the way: completely build amber9 with gcc 4.1 I needed to
change line 9 $AMBERHOME/src/arpack/stat.h from
       double precision t0, t1, t2, t3, t4, t5
to
       real t0, t1, t2, t3, t4, t5

...Maybe one of the fortran gurus will also give his opinion.

good luck
Andreas
