Fixed in CVS MAIN branch with fplib rewriting.
There are no plans to change 1.4 branch.

Today I have taken a file 'isnan-20050608.tar.gz' to check up. The file did not manage to be unpacked! Contents are completely destroyed! I have not found at myself an initial variant. I have not found at myself an initial variant and I send the following version.

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.
