Indeed from the man page notes I can read

NOTES
Note that these functions are obsolete.  C99 defines macros isfinite(),
isinf(), and isnan() (for all types) replacing them.  Further note that
the C99 isinf() has weaker guarantees on the return value.  See
fpclas-sify(3).

so probably ntop heck should be updated by using properly macros.
