Found it. The problem's in the MSVC project for the GNULIB utilities,
specifically in glob.c (well spotted, Kelly!). glob.c has several #ifdef
WINDOWS32, which is never defined. After defining the macro in the MSVC
project file, it compiles and runs properly.

I would suggest naming this binary 1.12.13a, committing the changes
(project file and version #) to a new branch based off the tag
cvs1-12-13. Sound good?

Yes, I'm working on using the existing sanity.sh under a Cygwin shell.
The sanity script passes all the tests for the tools.

At the moment, the big challenge is converting the UNIX path into the
correct Windows path, for example /tmp/cvs-sanity/cvsroot to
c:\cygwin\tmp\cvs-sanity\cvsroot. I suspect the next major hurdle will
be the one Derek mentioned - handling the different slashes.

On a tangent - I'm currently (ahem) `bash`ing my head trying to get some
simple stuff working <Jim ducks to avoid flying objects>. Any
suggestions for getting up to speed with shell programming? What I need
is something that will help me understand subtleties like scope of
variables. For example, in this code snippet:


echo $longest | sed 's:\(.*\)/\(.*\):\1 \2:' |
  read -s longer shorter

echo "$longest, $longer, $shorter"

$longer and $shorter do not retain their values outside the read
function. If I make it "echo {etc} | while read longer shorter; do" then
longer and shorter contain the expected values, but any changes I make
to $longest do not remain in effect past the "done" statement. Please
don't tell me the answer - point me at a reference that will explain it,
because I'm sure this will be just one of many subtleties I'll face.
