Hi Uli & Matt,

On many systems, the "make depend" step can fail to locate the mpif.h
header file (or other header files such as netcdf.inc) yet the mitgcmuv
binary will nonetheless build just fine.  Its a subtle point but the
dependency checker called by "make depend" doesn't always use exactly
the same header search paths as the C-preprocessor.  And what _does_
matter is whether your C-preprocessor locates all the necessary files.

To ensure that cpp (or whatever your C-preprocessor is called) can find
everything it needs, you can set additional header search paths in your
optfile with syntax such as:

  #####  beware of line wrap !!!
  INCLUDES='-I/usr/local/pkg/ifc/ifc-8.1.018/include 
   -I/usr/local/pkg/mpich/mpich-intel/include/'

which was taken directly from the optfile:

  MITgcm/tools/build_options/linux_ia32_ifc+mpi_itrda
