Greping objecct files strikes me as error-prone.
Well, yes, but I believe the test will work as stated. Do you
disagree? That is, do you believe it will ever generate an incorrect
result?
An alternative is to use the strings program if it is available; e.g.,
strings foo.o | grep 0123
However, a GNU configure script should not rely on the existence of
strings, according to
