Due to another recent change in raw-sha1-ng, I get a new warning when compiling with clang version 2.9: rawSHA1_ng_fmt.c:127:14: warning: unknown pragma ignored [-Wunknown-pragmas] # pragma GCC optimize 3 I don't know whether more recent clang versions support this pragma, so I wouldn't disable it for clang. I just wanted to let you know. Which version of gcc supports this pragma? clang 2.9 (tags/RELEASE_29/final) claims to be compatible with gcc 4.2.1. Frank Frank
