Compilation problem when using openmpi-1.3.3

[Rich Lee]

I found that the attached patch I created helped me in compiling
parallel-netcdf 1.1.0 with openmpi (version 1.2.7). Note that the patch
should apply to the original parallel-netcdf 1.1.0 distribution. It
contained addition fix (for C++ compiler) I reported early.

Best regards,
