In search of an ancient IEEE-754 floating point test suite

[Phil Budne]

Have you looked at http://www.math.utah.edu/~beebe/software/ieee/ ?
Which says:

    "All C programs can also be compiled with old-style Kernighan and
    Ritchie C. However, inasmuch as I now have access to only one such
    old compiler, with more than 35 others supporting 1989 Standard C,
    I no longer attempt to retain K&R compatibility in new code.

If you run into trouble, perhaps Nelson has older versions stashed away?
