ad dnl Process this file with autoconf to produce a configure script. dnl The ONLY thing this is used for is to configure for different dnl linux architectures and configurations, it is not used to make the dnl code more portable dnl You MUST have an environment that has all the POSIX functions and dnl some of the more popular bsd/sysv ones (like select).
