Just FYI, a "make distclean" (or any other "make" for that matter) won't
work until the configure script has been executed because that script
creates the makefiles.

Just FYI, the "assert()" C macro is disabled via the NDEBUG macro rather
than NODEBUG.

The above looks good, although to be consistent with the requested level
of optimization in the C, C++, and Fortran-77 compilers, you probably
want the F90FLAGS environment variable to contain "-O" rather than "-g".

I just built the netcdf-3.5-beta3 package on our AIX 4.3 system using
exactly the same environmental settings that you used:

    /tmp/netcdf-3.5-beta3/src: CC=/bin/xlc CPPFLAGS=-DNODEBUG CFLAGS=-O 
FC=/bin/xlf FFLAGS=-O CXX=/bin/xlC F90=/bin/xlf90 F90FLAGS="-g -qsuffix=f=f90" 
./configure &>configure.log

Everything went fine -- including the "make test".

The problem might be that we have different versions of the same C
development environment.  Here's the version of the C compiler that I
used (getting version information is non-trivial):

    $ (cd libsrc; /bin/xlc -c -O -I. -DNODEBUG -qLIST attr.c; \
    grep Version attr.lst | head -1; rm attr.lst)
    C for AIX Compiler Version 3.1.4.10 --- attr.c 06/27/00 15:23:07 (C)
