[PATCH portable] portable: build closefrom unconditionally
I think you should just not check the return value of closefrom(). It is void on Solaris where it originated, OpenBSD is the outlier here because it is a syscall. Or you can just set the close-on-exec flag for all the fds you open and avoid closefrom() altogether. - todd
