Portland Group has published recommendations for compiling netCDF with
their compilers:

  http://www.pgroup.com/resources/netcdf/netcdf362_pgi71.htm

and in that recommendation, they have set

  CFLAGS="-O2 -Msignextend -V"

before running the configure script.  I'm not sure how necessary the -O2
and -V are (I think that just prints the version), but we have tested the
4.0.1 version using the CFLAGS above on a 64-bit Linux platform with all
PG compilers, and it worked.  The exact settings we used were:

  CPPFLAGS="-DNDEBUG -DpgiFortran"
  CC=pgcc
  CFLAGS="-O2 -Msignextend -V"
  CXX=pgCC
  CXXFLAGS=-g 
  FC=pgf90 
  FCFLAGS=-g 
  F77=pgf90 
  FFLAGS="-O2 -w -V"

and the configure script was called as:

  ./configure --enable-netcdf-4 --with-hdf5=/upc/share/ed/local/shecky

before running

  make check install

The output from this working build is here:

As a side note, the cxx4 API is very incomplete and untested. It is
experimental. If you want to use it, count on having to debug and
improve it yourself. We hope to get the cxx4 API ready for the 4.2
release.  I recommend you omit --enable-cxx-4 unless you really need
it and are prepared to do some work on it.  That's why it's currently
disabled by default.

I hope this helps.
