Actually clang doesn't get updated *that* often, but there is a minor snag that one of llvm's config files (lib/clang/include/llvm/Config/config.h) includes <osreldate.h>, so each time __FreeBSD_version is bumped, quite a lot of dependencies get triggered... The version is only used for two checks: #if __FreeBSD_version >= 1000052 /* Define to 1 if you have the `backtrace' function. */ #define HAVE_BACKTRACE TRUE and: /* Define to 1 if you have the `futimens' function. */ #if __FreeBSD_version >= 1100056 #define HAVE_FUTIMENS 1 #endif Maybe the first check could be dropped, assuming that backtrace() is always available, but I'm not sure about futimens(). Is there any supported version of FreeBSD left that does *not* have it? -Dimitry
