The symbol "__eprintf" is part of the GNU C runtime library. Apparently,
the GNU C compiler was used to build your UDUNITS library. The native
Fortran-90 compiler, f90, does not know about the GNU C runtime library.
You must tell your linker to search the GNU C runtime libary. For
example:

    f90 ncep_hgt_1999.f -L/home3/NCEP/ncep/netcdf-3.4/lib \
    -L/home3/NCEP/ncep/udunits-1.11.7/lib -lnetcdf -ludunits \
    -I/home3/NCEP/ncep/udunits-1.11.7/include \
    -I/home3/NCEP/ncep/netcdf-3.4/include \
    -L/opt/gnu/lib/gcc-lib/sparc-sun-solaris2.6/2.95.2 -lgcc

Alternatively, you could rebuild the UDUNITS library using the native
development environment rather than the GNU development environment.
