You should install netcdf-232pl4 instead of netcdf-232pl2: it's more
recent.

I just built netcdf-232pl4 on our SunOS 4.1.4 system with the following
configure script settings:

    $ CC=gcc CXX=g++ ./configure

It went flawlessly.

The GNU C manual comes with the GNU C distribution as a `TeXinfo' file.
The GNU `info' utility is used to view the on-line manual.
Alternatively, the manual can be printed via tex(1).

I wouldn't use these settings: I'd use the ones I mentioned.

You shouldn't get this warning with the settings I mentioned.

Please let me know if this helps.
