cmp in test scripts

[John Poltorak]

Is there any way that autoconf can be used to handle cmp in test scripts?

Occasionally a test will fail because of the use of cmp to test 
differences between generated data and expected results due to line 
termination on DOS filesystems. If diff is used instead the test may 
succeed. 

What I'd like to see is some check to see if the use of cmp is valid and 
if not then maybe set CMP=diff ...
