Windows MSVC: 64bit compiler sees 2 export symbols

Browse Source 
The MSVC compiler sees a request for the main symbol (init__pyscopg) to be
exported twice during the build process and issues a warning in 64bit mode.
One symbol is from distutils exporting the library with the
build_ext.get_export_symbols() function, the other is from the #define
PyMODINIT_FUNC (define in pyport.h) that begins the main _psycopg module.
This patch overrides the get_export_symbols function and returns an empty
array of symbols to export if the compiler is MSVC.
