-@node Host, Target, Build Directories, What Configure Does
+Normally, @code{configure} builds @file{Makefile}'s and symbolic links
+in the same directory as the source files.  This is the typical
+@sc{un*x} way to build programs but it has limitations.  For instance,
+using this approach, you can only build for one host at a time.
+
+We refer to the directories in which @code{configure} builds
+@file{Makefile}'s as the @emph{build directories} or sometimes as
+@emph{objdir} because these are the directories in which @code{make}
+will build object files, among other things.
+
+The default build directory is the same as the source directory.
+
+You can change the build directory with a sequence like the following:
+
+@example
+mkdir @var{builddir}
+cd @var{builddir}
+configure @var{host} -srcdir=@var{sourcedirectory}
+@example
+
+where @var{builddir} is the directory in which you wish to build,
+@var{host} is the host for which you want to build, and
+@var{sourcedirectory} is the directory containing the source files.
+
+If you were to do this twice with different values for @var{builddir}
+and @vr{host}, then you could @code{make} for both at the same time.
+
+NOTE: The rest of this section describes the @code{-subdirs} feature for
+which support is at least temporarily suspended.  FIXME-soon.
+
+Another way to specify the build directory is with the @code{-subdirs}
+option.  For example:
+
+@example
+configure @var{host} -subdirs
+@end example
+
+Using this option, @code{configure} will create a subdirectory named
+@file{H-@var{host}} to act as the build directory for each source
+directory.
+
+Since building for multiple hosts is so common, @code{configure}
+recognizes this situation as special.  For example:
+
+@example
+configure @var{host1} @var{host2}
+@end example
+
+is precisely the same as:
+
+@example
+configure @var{host1} -subdirs
+configure @var{host2} -subdirs
+#end example
+
+That is, when configuring for multiple hosts or multiple targets,
+@code{-subdir} is assumed.
+
+When configuring for cross tools, that is, the host is not the target,
+as in:
+
+@example
+configure @var{host} +target=@var{targ} -subdirs
+@end example
+
+the subdirectories are named @file{X-@var{host}-@var{targ}}.  This is
+especially useful when configuring for multiple targets.
+
+If both @code{-subdirs} and @code{-srcdir=} are given, a tree that
+parallels the source directory structure is created in the current
+directory, except that the current directory represents the source
+directory itself, and the subdirectories are created in this directory
+tree rather than in the source directories.
+
+NOTE: previously, -subdirs built two level subdirectories as
+./H-host/T-target, created ./H-host/Makefile for building across all
+targets, ./Makefile for building across all hosts, and ./config.status
+and ./H-host/config.status for rebuilding these Makefiles.

-@node Target, Local Conventions, Host, What Configure Does
+The arguments to @code{configure} are @emph{hosts}.  By @emph{host} we
+mean the environment in which the source will be compiled.  This need
+not necessarily be the same as the actual physical machine involved,
+although it usually is.
+
+For example, if some obscure machine running an operating system other
+than @sc{un*x} actually had the @sc{gnu} @sc{posix} emulation libraries
+available, it would be possible to configure most @sc{gnu} source for a
+@sc{posix} system and build it on the obscure host.

+For more on this topic, see @xref{Host Environments, , cfg-paper, On
+Configuring Development Tools}.
+
+@node Target, Local Conventions, Host, Using Configure
 @section Target
 
+For building native development tools, or most of the other tools in the
+@sc{gnu} collection, you need not worry about the target.  The
+@emph{target} of a configuration defaults to the same as the
+@emph{host}.

+For building cross development tools, please see @xref{Building
+Development Environments, , cfg-paper, On Configuring Development

+

 @section Local Conventions
 
+If you find that a tool does not get configured to your liking or that
+@code{configure}'s conventions are not your local conventions, you
+should probably consider site specific Makefile fragments.  (see
+@xref{FIXME-now: site specific makefile fragments})
+
+These are probably not the right choice for options that can be set from
+the @code{configure} command line or for differences that are host or
+target dependent.

+suspended.

-@item Create Directories

-When configure is run with either of the 
+(see @xref{Build Directories}) When @code{configure} is run with the
+@code{-srcdir=} option, a directory tree is created that parallels the
+directory structure of the source directory except that the current
+directory is treated as the build directory for the source directory
+proper.  (see @xref{Invoking}).
+
+NOTE: support for @code{-subdirs} is at least temporarily suspended.
+
+When @code{configure} is run with the @code{-subdirs} option, a build
+directory is created in each source directory.
+
+If both @code{-subdirs} and @code{-srcdir=} are given, a tree that
+parallels the source directory structure is created in the current
+directory, except that the current directory represents the source
+directory itself, and the subdirectories are created in this directory
+tree rather than in the source directories.
+
+@item Generate Makefiles
+A makefile template, usually called @file{Makefile.in} from the source
+directory is copied to an output file in the build directory.  The
+output file is usually named @file{Makefile}.  A number of makefile
+macros are prepended to the output file.  If @code{-prefix=} or
+@code{-datadir=} were specified on the @code{configure} command line,
+then the makefile variables are set accordingly.  If host, target, or
+site, specific makefile fragments exist, they are inserted into the
+output file.  (see @xref{Makefiles, , , make, Makefiles})
+
+@item Generate .gdbinit
+If the source directory contains a .gdbinit file and the build directory
+is different from the source directory, a .gdbinit file is created in
+the build directory.  (see @xref{Command Files, , , gdb, Command Files})
+
+@item Make Symbolic Links
+Most directories have some symbolic links with generic names built
+pointing to specific files in the source directory.  If the system on
+which @code{configure} is run cannot support symbolic links, then hard
+links are used instead.
+
+@item Miscellaneous
+If the source directory has special needs, they are handled.  Usually
+there are none, but sometimes they involve changes to the output
+makefile.
+
+@item Generate config.status
+A shell script named @file{config.status} is created in the build
+directory.  This shell script, when run from the build directory, will
+reconfigure the build directory except that subdirectories are not
+reconfigured.  This is most often used by @code{make} to rebuild the
+output makefile.  (see @xref{Top, , , bash})
+
+@item Recursion
+If the source directory has subdirectories that should also be
+configured, then @code{configure} is called for each.
