If you want to check for a Glibc feature (regardless of which kernel we're using), the following is enough: #ifdef __GLIBC__ However note that what usually happens is that other libraries which are used on Linux and are similar to Glibc implement the same features and will want to match this #ifdef too. Thus removing the "__linux__" although it might be strictly correct may cause a regression. I usually just avoid causing the regression by leaving the __linux__ in, even if the feature we're checking has nothing to do with kernel. -- Robert Millan -- To UNSUBSCRIBE, email to debian-java-requ...@lists.debian.org with a subject of "unsubscribe".
