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.
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.
14 ## For more information on these two systems, check out the documentation
15 ## for 'Autoconf' (autoconf.texi) and 'Configure' (configure.texi).

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