The `static' files in question being the reference data, provided with 
the package, for what the output of the tests should be.

Yep.  I've noticed this too.  At one time, while attempting to build a 
native version of GNU m4, every one of its tests failed; I can't 
remember now, just how many tests were involved, but I think it was 
around 80.  All but two of the failures were directly attributable to 
this `\n' vs. `\r\n' distinction.
