OK, *NOW* I think I see it.

You need to set -no-second-underscore in both FFLAGS (for F77 API) and in
FCFLAGS (for F90 API).

You have this:
checking CPPFLAGS... -DpgiFortran
checking CC CFLAGS... gcc -g -O2
checking type gcc... gcc is /usr/bin/gcc
checking CXX... g++
checking CXXFLAGS... -g -O2
checking type g++... g++ is /usr/bin/g++
checking FC... g95
checking FFLAGS... -fno-second-underscore
checking type g95... g95 is /usr/local/bin/g95
checking F90... g95
checking FCFLAGS... -g -O2

So you are setting -fno-second-underscore in FFLAGS, which causes it to work
for the F77 API, but not FCFLAGS, for the F90 API. This results in an F90
compile like this:

make[2]: Entering directory
`/data/zender/tmp/netcdf-4.0-snapshot2008092910/f90'
g95 -I../libsrc4 -I.  -g -O2 -c -o typeSizes.o typeSizes.f90

So that's not good!

I have tested this on my machine, and it worked for me like this:
 CPPFLAGS=-DpgiFortran FC=g95 FFLAGS=-fno-second-underscore
 FCFLAGS=-fno-second-underscore ./configure && make check

I have added this test case to my nightly snapshot testing, so you can see the
full output on the snapshot test page. Search for no-second-underscore.

I hope this will finally solve your problem, but if not, please let me know.

Thanks,
