Though I haven't built the netCDF package on a Linux system and don't
routinely use the gcc(1) compiler, I have built the package on many
different systems.  It appears to me that your gcc(1) installation is
incorrect in some way: system header files are attempting to include
linux-specific headers files which the compiler can't find.  For
example, the system header file `/usr/include/stdlib.h' appears to be
trying to include the header file `linux/errno.h'.  Does it?

I suggest the following:

    1.  Verify that the system header files (in `/usr/include') are
        attempting to include header files in a `linux/' subdirectory.

    2.  If true, then attempt to locate the `linux/' subdirectory (is it
        under `/usr/include/'?).

    3.  Once you know where that directory is, try specifying it in the
        value of the CPPFLAGS variable before running the `configure'
        script.  For example, say the the directory
        `/usr/local/gcc/linux' exists and contains the header files
        `errno.h' and `types.h', then re-invoke the `configure' script
        in the following way:

            $ CC=gcc CPPFLAGS=-I/usr/local/gcc ./configure --prefix=/usr/local

    4.  Then try a re-make(1).

Please let me know if this helps.
