This is the second batch of makefile changes. Libg++ makefiles were
checked in earlier. These are Makefiles relevant to the progressive
release currently in progress.
* added exec_prefix
* default bindir now exec_prefix/bin
* default libdir now exec_prefix/lib
* default mandir now prefix/man
* default infodir now prefix/info
* added oldincludedir, default NULL
* remove all traces of the old -subdirs and -namesubdir support,
including code, for loops, and all subdir/unsubdir stuff.
* remove old style staging targets {de-}stage[1234], comparison,
bootstrapN, from all but the bootstrappable tools.
* added check targets.
* removed any "Last Mod" lines.
* forced copyrights to '92 and shifted some from Cygnus to FSF.
* added tooldir and program_prefix where needed.
* updated texinfo and man pages, removed all references to multiple
hosts or targets.

|

|

@code{configure} prepares source directories for building working
|
||||
programs. A program cannot be built until its source has been
|
||||
configured. When configure runs, it does the following things for each source
|
||||
directory for each host and target combination.

When you run @code{configure} with the @code{-subdirs} option, it
|

creates a build subdirectory in each source directory.

@file{Makefile.in}, is copied to an output file in the build directory.

Another way to specify the build directory is with the @samp{-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, configuring for multiple hosts or multiple targets implies
|
||||
@samp{-subdirs}.
|
||||
|
||||
When configuring for cross tools (the converse of native tools: when the
|
||||
host is not the target), as in:
|
||||
|
||||
@example
|
||||
configure @var{host} +target=@var{targ} -subdirs
|
||||
@end example
|
||||
|
||||
@noindent
|
||||
the subdirectories are named @file{X-@var{host}-@var{targ}}. This is
|
||||
especially useful when configuring for multiple targets.
|
||||
|
||||
If you use both @samp{-subdirs} and @samp{-srcdir=}, a tree that
|
||||
parallels the source directory structure is created in the current
|
||||
directory, and the subdirectories are created in this directory
|
||||
tree rather than in the source directories.
|
||||
|
||||
@emph{NOTE:} previously, @samp{-subdirs} built two-level subdirectories
|
||||
as @file{./H-@var{host}/T-@var{target}}, created
|
||||
@file{./H-@var{host}/Makefile} for building across all targets,
