static NyHeapDef nysets_heapdefs[] = {
    {0, 0, (NyHeapDef_SizeGetter) mutbitset_indisize},
    {0, 0, 0, cplbitset_traverse},
    {0, 0, nodeset_indisize,  nodeset_traverse, nodeset_relate},
    {0}
};

    nysets_heapdefs[0].type = &NyMutBitSet_Type;
    nysets_heapdefs[1].type = &NyCplBitSet_Type;
    nysets_heapdefs[2].type = &NyNodeSet_Type;

The code looks fine to me and compiles with GCC 4.6. It seems your GCC
chokes on "nysets_heapdefs[0].type = &NyMutBitSet_Type;". It's not a
file local static but an extern declaration. Are you sure that you are
using a recent version of GCC 4.x? I had some issues with GCC 3.x in the
past. Cygwin has GCC 3.x as default gcc.

For Python 2.6 you can use the free VS 2008 Express version. I've
compiled guppy for 32bit Python 2.7 a couple of days ago w/o any issue
