* Suppress incorrect link warnings for NSS symbolsChris Metcalf2012-10-301-1/+1
| | | | | | | | | When glibc is built with --enable-static-nss, the warning that using NSS symbols requires the nss shared objects to be present is no longer true, as those symbols are built into libc. Suppress the warning for those symbols by providing a new macro (nss_interface_function) for the NSS functions that is defined as static_link_warning in the normal case, and empty for static NSS.
* Fix fma missing underflows and bad results for some subnormal results (bugs ↵Joseph Myers2012-10-303-42/+24
