George,

Your Fortran compiler seems different from mine.  In executing the
configure script, I got the following excerpts:

    checking if Fortran compiler handles *.F files... yes
    ...
    checking if Fortran "real" is C "float"... yes
    checking if Fortran "doubleprecision" is C "double"... yes

whereas you got the following:

    checking if Fortran compiler handles *.F files... no
    checking for Fortran preprocessor... cc -E
    ...
    checking if Fortran "doubleprecision" is C "double"... no
    checking if Fortran "doubleprecision" is C "float"... no

The last two above are particularly troubling: they indicate that there
is no C data type equivalent to a Fortran "doubleprecision".  I've
seen this before: it happens if the "-dp" option is omitted from the
FFLAGS environment variable prior to executing the configure script
from scratch (I just verified this on our C90).  You said, however,
that your FFLAGS environment variable contained the "-dp" option when
you re-executed the configure script -- so there must be something else
going on.  I'm at a loss, however, to come up with what that something
could be.

Would you be willing to compile and execute some small test programs to
uncover the problem?

My version of the Fortran compiler is

    $ f90 -V
    Cray CF90 Version 3.1.0.0 09/22/99 10:51:33

What's yours?
