[GiNaC-devel] Another MSVC error

Here's another one, and I suspect it must be connected with the C2766. lst.h(35): error C2512: 'GiNaC::class_info<GiNaC::registered_class_options>': no appropriate default constructor available Because to fix this error, I supplied the requested default constructor in class_info.h line 48: class_info() {} which forces me to supply another default constructor class_info.h(48): error C2512: 'GiNaC::registered_class_options': no appropriate default constructor available registrar.h line 85: registered_class_options() {} and then the "no appropriate default constructor" errors go away but later on in the compile the C2766 turns up.
