You shouldn't do that!

MS-Windows *needs* the .exe extension, to mark the application file as executable,
since there is no file attribute for this purpose.  A Cygwin application may
be invoked directly from the Windows environment, even without having the Cygwin
bash.exe shell running, but Windows itself needs to know that the file is executable;
the .exe extension is what tells it!

Although, the Cygwin bash.exe, and the MSYS sh.exe for that matter, may *allow*
you to drop the extension, and still be able to execute the application, you
will not then be able to invoke it from a native MS-Windows environment.

As I stated yesterday, the proper way to handle this is to construct the Makefile
so that the extension is handled by a *variable*, in the manner employed by
GNU autoconf, with its $(EXEEXT) variable -- and why else would you *need* to
remove the extension?  The exec and spawn functions used by both Cygwin and
MinGW will append it automatically to any bare file name specified, when searching
for a program file to invoke a process!
