It's an old warning and is present because Octave used to rely
entirely on the system functions for reading floating point values,
and not all systems could read NaN and Inf values stored in text
files.  Now Octave scans the files for Inf/NaN/NA before reading float
values with the system library, so it should always be possible to
reload text files that contain Inf/NaN/NA values.

For now, save data in binary formats?  Edit the Octave sources and
rebuild Octave?

Since the warning was not issued consistently, and it is more or less
obsolete, I'm removing it from my sources so it should not appear in
Octave 3.0.
