There is a mismatch between 'isnan', 'isinf' and avr-libc/libm arithmetic.
Attached file 'bug.c' illustratets this.
Also in tarball new variant is present.

Rationale: `isnan' must return non-zero value for all numbers, that
are rejected by libm/avr-libc.  'isinf', probably, should return always 0 as
arithmetics with Inf is not realized.
