Hi,

I just found a bug (or at least a discrepancy between doc and src) in newlib's libm, files mathfp/s_logarithm.c and mathfp/sf_logarithm.c:

There the docs at the beginning of the files say, log(0) returns -Inf, what the gawk test suite would also expect btw, but clearly the implementation doesn't return -Inf, but NaN instead.

Martin

A fix has been made. Thanks.
