   1 dnl Process this file with autoconf to produce a configure script.
   2 dnl The ONLY thing this is used for is to configure for different
   3 dnl linux architectures and configurations, it is not used to make the
   4 dnl code more portable
   5
   6 dnl You MUST have an environment that has all the POSIX functions and
   7 dnl some of the more populare bsd/sysv ones (like select). You'll also
   8 dnl need a C++ compiler that is semi-standard conformant, exceptions are
   9 dnl not used but STL is.
