I assume you're using netCDF version 3.4, the latest released version.
In the INSTALL file are instructions for building netCDF on HPUX
systems.  In particular, it recommends setting some environment
variables before you run the configure script:

  CC=/bin/c89
  CPPFLAGS='-DNDEBUG -D_HPUX_SOURCE -w' # "-w" suppresses ignorable warnings
  CFLAGS=-O
  FC=/opt/fortran/bin/fort77            # might be /usr/bin/fort77 instead
  FFLAGS='-O -w'
  CXX=/usr/bin/CC

I think the "-D_HPUX_SOURCE" will fix the problem you are seeing.  How
you set the environment variables differs depending on what shell you
are using.  See

  http://www.unidata.ucar.edu/packages/netcdf/INSTALL 

in case you need an explanation of how to set the environment
variables.  Make sure you delete the file "config.cache", if it
exists, and "make clean".  Then rerun the configure script.  This will
set up all your Makefiles, so you should just need to invoke "make
all", "make test", and "make install".

If there are still problems, please send us the information listed in
the "REPORTING PROBLEMS" section at the end of the INSTALL file.  Thanks.
