I assume that CentOS 5.5 uses some version of glibc before version 2.6. The three functions you mention are not supported in older versions of glibc. Fortunately, they are not called anywhere else in the library, so this patch takes the easy way out and simply removes them. Bootstrapped and ran Go testsuite on x86_64-unknown-linux-gnu. Committed to mainline. Ian
