Incidentally, I have already thought of doing something like this:

# ...
Path="$(cygpath -pw "${PATH}");$(cygpath -pw "${LD_LIBRARY_PATH}")"
export Path
exec "${0}.bat" "${Path}" ${1+"${@}"}

Where "${0}.bat" may be something like:

set Path=%1
shift
%1 %2 %3 ...

But this does not work, since some of my arguments may contain spaces 
(which are not parsed correctly in the batch file), and batch files 
have an unusable limit on the number of useful arguments they can parse 
(%* is *not* affected by the shift batch file command, nor does it 
properly quote arguments). Using "%1" "%2" "%3" ... does not help 
either.

In short, I do not believe that batch files are a viable solution to my 
problem (though this may stem from my ignorance on how to write them 
robustly). Either way, I would like to find an alternate solution.
