Under MSYS bash.exe if I use the touch command I only get 1-second
resolution when reading the results.

bash.exe-3.1$ touch touch1.test touch2.test
bash.exe-3.1$ ls --full-time touch*.test
-rw-r--r-- 1 wine 544 0 2013-10-12 13:57:58.000000000 -0700 touch1.test
-rw-r--r-- 1 wine 544 0 2013-10-12 13:57:58.000000000 -0700 touch2.test

Would somebody be willing to make the above test for MSYS on
the Microsoft version of Windows (which I don't have access to) to see
if time stamps are being read with 1-second resolution as above. That test
should help distinguish whether this is a Wine issue or else an MSYS

I have also done some tests with the MSYS find.exe and make.exe
commands, and in all cases touch2.test is not newer than touch1.text.
This can be an important issue for the make command where one-second
time resolution can potentially screw up file dependencies.

If I use the equivalent Linux ls (and find and make) commands to read the
time stamps on the above files, then touch2.test is newer than touch1.text,

wine@raven> ls --full-time touch*.test
-rw-r--r-- 1 wine wine 0 2013-10-12 13:57:58.391000000 -0700 touch1.test
-rw-r--r-- 1 wine wine 0 2013-10-12 13:57:58.408000000 -0700 touch2.test

So I think this implies the MSYS touch.exe command is writing
high-resolution (i.e., millisecond) time stamps, and it is only
reading that high-resolution time stamp that seems to be an
issue for MSYS on Wine.

Sure -- seems to be a MSYS issue though:
