The work-around for a similar problem with tp_new is described here:
http://docs.python.org/ext/dnt-basics.html
"On some platforms or compilers, we can't statically initialize a structure member with a function defined in another C module, so, instead, we'll assign the tp_new slot in the module initialization function just before calling PyType_Ready()"
So in BPyFloatType_Init(), you put the initialization for "BPyFloat_Type.tp_base = &PyFloat_Type;"

Hi, this compiles fine on linux but on windows with MSVC8 it gives an error on this line.
&PyFloat_Type, /* tp_base */ saying that it cant initialize because &PyFloat_Type is not a constant.
Has anyone else had this problem or know a workaround?
