Thanks Lars, I completely missed this point.  I really read `-ef' as
`-e -f', which makes no sense anyway :)

Now with your remark in mind, given the snippet which uses it

+  if test conftest -ef conftest.exe; then
+    # Prefer .exe over empty suffix.
+    ac_cv_exeext=.exe
+  else
+    ac_cv_exeext=
+  fi

I think it is OK to use it, since the fall back is TRT.  The only
problem is with error messages from test, so I'd propose:

+  if (test conftest -ef conftest.exe) >/dev/null 2>&1; then
+    # Prefer .exe over empty suffix.
+    ac_cv_exeext=.exe
+  else
+    ac_cv_exeext=
+  fi
