You have a very old version of AIX (3.2).  We have AIX 4.2 here, so we
cannot duplicate the problem, but I found an earlier support message
using the search through the netCDF support email archive that's
available at the bottom of the netCDF home page.  I just search for
"Undeclared identifier O_RDWR", and it finds the following support
reply for a similar AIX 3.5 problem:

   http://www.unidata.ucar.edu/glimpse/netcdf/2265

That suggests the following will work:

... the posixio.c module requires not only ANSI but also POSIX
defines, so you need the -D_POSIX_SOURCE flag on compile lines.  To do
this:

  1.  rm config.cache
  2.  define CPPFLAGS as "-D_POSIX_SOURCE -DNDEBUG" in your environment
      before invoking configure.
  3.  make clean
  4.  Run the configure script: ./configure
  5.  make all
  6.  make test
  7.  make install

If you run into more problems with the above, please send the details
to address@hidden.  Thanks.
