in reply to exec not working?
On further investigation, I find that exec no longer works
:) Ah yes, and you are the first person to have noticed this bug since 1994. Sure.
Even though I can't reproduce what you see, I'm confident it is not likely that exec is broken, especially seeing how it gives you a warning, indicating that its working as designed :)
runperl.bat is probably as broken as it ever , much like pl2bat, it doesn't use absolute paths (for one $^X)
It should be simple to turn runperl.bat into runperl.exe (and runwperl.exe, respectively)
