No, so I wrote my own:

    $ version 'C:\Program Files\Microsoft Office\OFFICE11\WINPROJ.EXE'
    Required Information:
        ProductVersion = 11.0.2003.816
        FileVersion = 11.0.2003.816
    Optional Information:

    $ cygversion /mnt/c/Program\ Files/Microsoft\ Office/OFFICE11/WINPROJ.EXE 
    Required Information:
        ProductVersion = 11.0.2003.816
        FileVersion = 11.0.2003.816
    Optional Information:

See attached for the source and Makefile.

Note the Makefile builds two executables:

    version.exe:    Mingw executable
    cygversion.exe: Cygwin executable
