Subject: [PATCH] Changes to netlist.h

Changes so "Microsoft Visual Studio Express 2015 RC Web" could build it without a bunch of runtime errors and crashes during regression testing.  When declaring an bitfield variable of type enum in a struct, the enum has to have an underlying integer type for MSVC++ when compiling a C++ file, and for these cases, it had to be unsigned integer for everything to work okay during regression testing.
