I was wrong. Only some improvement using the cygwin1-20110829.dll.bz2 snapshot. Problems still exist when trying to check in a file with RCS on this Windows share.
Annotated test example below. Apologies for not being brief. Any ideas appreciated. However, progress has been made with the 0829 snapshot, at least I can create files on this share...... # 1 - Comments: Verify the version of cygwin1.dll: Fri Sep 16 10:24:20 (kchristian@laptop-pc) /cygdrive/z>uname -a CYGWIN_NT-5.1 laptop-pc 1.7.10s(0.251/5/3) 20110829 15:53:50 i686 Cygwin # 2 - Comments: Create a directory tree on the file share: Fri Sep 16 10:24:29 (kchristian@laptop-pc) /cygdrive/z>mkdir -p foo/bar/baz # 3 - Comments: Change to the "leaf" directory: Fri Sep 16 10:25:33 (kchristian@laptop-pc) /cygdrive/z>cd foo/bar/baz # 4 - Comments: Create a test file: Fri Sep 16 10:25:52 (kchristian@laptop-pc) /cygdrive/z/foo/bar/baz>pwd > testfile.1 # 5 - Comments: Cat the file to verify its contents: Fri Sep 16 10:26:05 (kchristian@laptop-pc) /cygdrive/z/foo/bar/baz>cat testfile.1 /cygdrive/z/foo/bar/baz # 6 - Comments: Show file permissions and ownership: Fri Sep 16 10:27:58 (kchristian@laptop-pc) /cygdrive/z/foo/bar/baz>ls -l testfile.1 -rwx------+ 1 kchristian Domain Users 24 Sep 16 10:26 testfile.1 # 7 - Comments: See what Windows rights are: Fri Sep 16 10:28:01 (kchristian@laptop-pc) /cygdrive/z/foo/bar/baz>cacls testfile.1 Z:\foo\bar\baz\testfile.1 COMPANY_XYZ\kchristian:C BUILTIN\Administrators:F NT AUTHORITY\SYSTEM:F # 8 - Comments: Create an RCS directory.
