I had a look at cygstart, but it doesn't even try to be commandline-compatible with Microsoft's start.exe. Oh, well.
I've verified that this implementation of start can do both start notepad and start foo.txt and that it obeys all the options obeyed by WindowsMe's start.exe. It also implements the /L option to print out the LGPL. (Do we have a convention for what this option, required by the LGPL, should be?)
I'd rather compile it as a .exe rather than a winelib app - is there a way to do that in the Wine tree? Also, what do I have to do to cause the resulting .exe to end up as %windir%/command/start.exe, so it's in the same place as it is in real Microsoft Windows?
BTW, to make 'start foo.txt' work, you need the registry entries
[HKEY_CLASSES_ROOT.txt] @="txtfile" "Content Type"="text/plain"
[HKEY_CLASSES_ROOT\txtfile\shell\open\command] @="C:\WINDOWS\NOTEPAD.EXE %1"
I verified that removing either of these on WinMe caused 'start foo.txt' to fail.
I did not verify that, when you use the /w flag, the exit status of the subprocess is returned in the same way as it's done in Windows.
Thanks, Dan
