Hi,

If you're referring to the Cygwin problem:

  Making `test' in directory [build directory]
   ..
  cmp test.nc test_nc.sav
  test.nc test_nc.sav differ: char 1545, line 5

it has nothing to do with Fortran 90 or g77, because it occurs in a
test involving only the C interface.  The output you got from running
the "configure" script:

  ...
  checking "g77" as Fortran-90 compiler... failed to build test program
  checking for xlf90... no
  checking for f90... no
  configure: warning: Could not find working Fortran-90 compiler
  configure: warning: The Fortran-90 interface will not be built

is not an indication of an error.  It just means you didn't use an
environment variable to specify a Fortran 90 compiler.  In this case
the configure script looks around for some likely suspects but if none
of them will properly compile a Fortran 90 program, it just continues
with the build, skipping the step of building and testing a Fortran 90
interface.
