bug#16252: 24.3.50; `report-emacs-bug' is now broken: (error "ShellExecute failed: The system cannot find the file specified.")

[Drew Adams]

[Note: The build noted below is the one regarding this bug report.  I'm
using an older build to report the bug, which is about the fact that I
can no longer use `report-emacs-bug'.]

This is the backtrace I got for `report-emacs-bug' (using my setup, not
emacs -Q):

Debugger entered--Lisp error: (error "ShellExecute failed: The system cannot 
find the file specified.")
