Visual Studio .NET build fails with error :
'nurbs++-3.0.11\matrix\barray2d_hpoint.cpp(35) : error
C2248: 'PLib::Basic2DArray<T>::m' : cannot access
protected member declared in class 'PLib::Basic2DArray<T>'
replacing the line
#undef HAVE_ISO_FRIEND_DECL
with
#define HAVE_ISO_FRIEND_DECL 1
in include/plib_config.h worked for me.
Maybe changes should be made to include/plib_config.h.vc,
or a new file should be made to match vs .net...
