The problem is the printf runtime. There is no good way to detect the support without running a test program and for a library that is explicitly used in many cross-compilation environments, that's a problem. > The following diff relieves it of this misery (but can't be sent > upѕtream, as it is too aggressive). I think it might be a good idea to try again. Since C++11 support made much of the runtime parts of C99 mandatory, even Microsoft had to adopt and they were the last big holdout. I don't know how ancient the systems are that expat targets, but asking seems to be a reasonable idea nowadays. Joerg
