I have this really wierd/Bizarre situation, and wonder
if anyone else has stumbled upon this:

I have set /usr/src to be a managed link and it's located
at c:\cygmanaged\src

I have a directory /usr/src/cygwin-equivs/cygwin-base
and under it there are some additional directories.

the thing thats causing me some wierd grief is that 
fhandler_disk_file::readdir is telling me about a file that it sees
that DOES NOT exist.  And, it only does it when in a 
grandparent directory.  This causes find to exit with:  

        strace --mask=all --output=strace.out find . -type f -a \( -name \#\*\#
-o -name \*\~ -o -name DEADJOE -o -name \*.orig -o -name \*.rej -o -name \*.bak
-o -name .\*.orig -o -name .\*.rej -o -name .SUMS -o -name TAGS -o -name core -o
 \( -path \*/.deps/\* -a -name \*.P \) \) -print
find: ./debian/README.Debian.in: No such file or directory

I have modified fhandler_disk_file::readdir to print an additional output
line, and here is the snippet that I'm referring to:

  121 1667396 [main] find 6456 closedir: 0 = closedir (0x22EAA8)

What's so bizarre is that the file README.Debian.in DOES NOT exist.

Does anyone have any idea where FindNextFileA is getting this extra file from?

Oh yeah, if I do this very same command down one directory, it works as expected, and does not
return the extra file.  Go Figure.
