Two changes have to be made to file ngspice-26/src/include/ngspice/ngspice.h

comment out line 179

//#define isnan _isnan

and add e.g. at line 201

// undo a #define bool _Bool in MS Visual Studio 2015
#if defined(bool)
#undef bool
#endif

Then ngspice.dll will result from compilation with VS2015.
