guidod's Miscellaneous (released)
if the current configure was run within the srcdir then we move all
configure-files into a subdir and let the configure steps continue
there. We provide an option --disable-builddir to suppress the move
into a separate builddir.
Defaults:
$1 = $host (overridden with $HOST)
$2 = Makefile.mk
$3 = -all
This macro must be called before AM_INIT_AUTOMAKE.
it creates a default toplevel srcdir Makefile from the information
found in the created toplevel builddir Makefile. It just copies the
variables and rule-targets, each extended with a default
rule-execution that recurses into the build directory of the
current "HOST". You can override the auto-dection through
`config.guess` and build-time of course, as in
make HOST=i386-mingw-cross
which can of course set at configure time as well using
configure --host=i386-mingw-cross
After the default has been created, additional rules can be
appended that will not just recurse into the subdirectories and
only ever exist in the srcdir toplevel makefile - these parts are
read from the $2 = Makefile.mk file
The automatic rules are usually scanning the toplevel Makefile for
lines like '#### $host |$builddir' to recognize the place where to
recurse into. Usually, the last one is the only one used. However,
almost all targets have an additional "*-all" rule which makes the
script to recurse into _all_ variants of the current HOST (!!)
setting. The "-all" suffix can be overriden for the macro as well.
a special rule is only given for things like "dist" that will copy
the tarball from the builddir to the sourcedir (or $(PUB)) for
reason of convenience.
