Modified Files:
src/lib/libm/src: k_standard.c
Log Message:
let log(<0) return NaN rather than -inf in POSIX/XOPEN modes, as
requested in PR lib/41931 by Havard Eidnes (the PR refers to POSIX,
the OSF/1 manpage suggests that XOPEN should behave that way too)
being here, do the same to log10 and log2
