use camel_mkdir(0777) rather than 0777 & st.st_mode which isn't set
2004-01-21 Not Zed <NotZed@Ximian.com> * em-migrate.c (cp_r): use camel_mkdir(0777) rather than 0777 & st.st_mode which isn't set anyway. (cp): use simple 0666 for the mode open, and then chmod after. (cp): check the return code of close, not just fsync. (cp): dont use fd[0] and fd[1] when we really just want simple variables, rename to readfd and writefd. svn path=/trunk/; revision=24347
