Where are NO_WNOHANG, NO_GETPASS, NO_SELECT, NO_SIGCHLD, NO_EXECVE etc in your 
list? A condition on MINGW32 is certainly sufficient.

I agree.

openlog() etc. is only one problem in git-daemon. It also depends on SIGCHLD, 
a non-blocking waitpid, and a lot more. The patch that is in 4msysgit.git 
allows only a single connection, IIRC, after which it terminates. But I also 
think that git-daemon can be made more complete on Windows, but it certainly 
requires a major surgery.
