   4 dnl linux architectures and configurations, it is not used to make the

   7 dnl You MUST have an environment that has all the POSIX functions and
   8 dnl some of the more populare bsd/sysv ones (like select). You'll also
   9 dnl need a C++ compiler that is semi-standard conformant, exceptions are
