   4 ## This file is a shell script fragment that supplies the information
   5 ## necessary to tailor a template configure script into the configure
   6 ## script appropriate for this directory.  For more information, check
   7 ## any existing configure script.
   8
   9 ## Be warned, there are two types of configure.in files.  There are those
  10 ## used by Autoconf, which are macros which are expanded into a configure
  11 ## script by autoconf.  The other sort, of which this is one, is executed
  12 ## by Cygnus configure.
  13
  14 ## For more information on these two systems, check out the documentation
  15 ## for 'Autoconf' (autoconf.texi) and 'Configure' (configure.texi).

  36 ### or a host dependent tool.  Then put it into the appropriate list
  37 ### (library or tools, host or target), doing a dependency sort.  For
  38 ### example, gdb requires that byacc (or bison) be built first, so it is in
  39 ### the ${host_tools} list after byacc and bison.
