However, as specified in the above links, one must call close() when done with every pymongo ReplicaSetConnection object, otherwise it will leave a bunch of zombie processes floating around (wtf pymongo). This sort of behavior isn't supported very well in Ming (it

I am using the rubenvb version of c++ (see version in subject, yes I'm building for 64bit) on Windows 7 and I'm having a problem using _BitScanForward64. Some sample code looks like this: int __cdecl main(int argc, char* argv[]) { DWORD d = (DWORD)atoi(argv[1]); DWORD ix, ix2; ix2 = _BitScanForward64(&ix, d); printf("bsf %u %u\n", ix, ix2); } I am compiling with: "C:\Program Files\gcc2\mingw64\bin\c++.exe" -o iTot.exe -mno-ms-bitfields -march
