OK, did that. With the `augmented' cygwin1.dll in place, my `strace ls' now says (excerpted): -------------------------------------------------------------------- 1481 230803 [main] ls 5132 path_conv::check: this->path(h:\), has_acls(0) 562 231365 [main] ls 5132 build_fh_pc: fh 0x61168D40 7242 238607 [main] ls 5132 fhandler_disk_file::opendir: 0x6857F0 = opendir (/cygdrive/h) 934 239541 [main] ls 5132 fhandler_disk_file::readdir: NtQueryDirectoryFile failed, status 0xC00000BB, win32 error 50 526 240067 [main] ls 5132 fhandler_disk_file::readdir: NtQueryDirectoryFile failed, status 0xC00000BB, win32 error 50 489 240556 [main] ls 5132 geterrno_from_win_error: windows error 50 == errno 88 608 241164 [main] ls 5132 fhandler_disk_file::readdir: 0 = readdir (0x6857F0, 0x22C6D4) (.) 1026 242190 [main] ls 5132 fhandler_disk_file::readdir: NtQueryDirectoryFile failed, status 0xC00000BB, win32 error 50 515 242705 [main] ls 5132 fhandler_disk_file::readdir: NtQueryDirectoryFile failed, status 0xC00000BB, win32 error 50 593 243298 [main] ls 5132 geterrno_from_win_error: windows error 50 == errno 88 -------------------------------------------------------------------- and is otherwise as before, as far as I can tell. I trust that was required? I haven't tried running against a snapshot build yet, as suggested in your later response. -- SAm. -- Academic Excellence at the Heart of Scotland.
