Bummer, then something else is wrong.

Looks like the executable is fine, then. Maybe it's a virus scanner
interfering, even though you said you've exempted things?  Also, are you
sure you are getting the correct m4?  What does:

$ type m4

say?  What about trying to execute it by absolute path:

$ /bin/m4 --version
$ /cygdrive/c/Windows/KSR/bin/m4 --version

Could it be a collision between a non-executable file named 'm4' vs. the
normal 'm4.exe' that is confusing cygwin .exe magic?  Are you sure that
nothing is messing with PATH and picking up a bogus m4 earlier in the
lookup process?
