[PD-dev] building iemnet on Windows and OS X

[Hans-Christoph Steiner]

Martin's 'net' library builds on all platforms, so you could check there for differences.  On Ubuntu, 'meld' is an awesome GUI tool for seeing the differences between versions of a file. 'opendiff' aka FileMerge is a similarly awesome tool on Mac OS X.
