Your other points (in the previous email) are pretty valid -- I'm going to try to initiate some conversations with the Cygwin developers.
If they consider the command line parsing as-is to be "to spec" (I have yet to _find_ any spec for argument parsing), then there is really no choice but to make make work to that spec -- e.g. if they say that when you call sh.exe from a DOS/Windows program, you _have to format arguments this way_, then, well, make has to format arguments this way. If they see room for a fix -- then there is no trouble with make at all. I'll see how that goes. In case there are cygwin developers on this list, I won't say anything too mean - but having followed development and read their mailing list archives, I am not encouraged. Just to be clear, though, make runs a very small set of programs directly. Remember that almost all programs are invoked by make via ' sh.exe -c "command" '-- and the invocation code/command line generation can tell that it's running sh.exe (and not some other program). There is in fact some logic already that determines whether or not make is running the shell or not (other things it runs include echo and make itself). Thus, while you're right that the make code can't tell whether everything it runs is a Cygwin binary, it does know about the special case of sh.exe being a cygwin binary - and that covers most of the cases.
