Obsolete `config.status' Invocation
===================================

   `config.status' now supports arguments to specify the files to
instantiate, see *Note config.status Invocation::, for more details.
Before, environment variables had to be used.

 - Variable: CONFIG_COMMANDS
     The tags of the commands to execute.  The default is the arguments
     given to `AC_OUTPUT' and `AC_CONFIG_COMMANDS' in `configure.ac'.

 - Variable: CONFIG_FILES
     The files in which to perform `@VARIABLE@' substitutions.  The
     default is the arguments given to `AC_OUTPUT' and
     `AC_CONFIG_FILES' in `configure.ac'.

 - Variable: CONFIG_HEADERS
     The files in which to substitute C `#define' statements.  The
     default is the arguments given to `AC_CONFIG_HEADERS'; if that
     macro was not called, `config.status' ignores this variable.

 - Variable: CONFIG_LINKS
     The symbolic links to establish.  The default is the arguments
     given to `AC_CONFIG_LINKS'; if that macro was not called,
     `config.status' ignores this variable.

   In *Note config.status Invocation::, using this old interface, the
example would be:

     config.h: stamp-h
     stamp-h: config.h.in config.status
             CONFIG_COMMANDS= CONFIG_LINKS= CONFIG_FILES= \
               CONFIG_HEADERS=config.h ./config.status
             echo > stamp-h
     
     Makefile: Makefile.in config.status
             CONFIG_COMMANDS= CONFIG_LINKS= CONFIG_HEADERS= \
               CONFIG_FILES=Makefile ./config.status

(If `configure.ac' does not call `AC_CONFIG_HEADERS', there is no need
to set `CONFIG_HEADERS' in the `make' rules, equally for
`CONFIG_COMMANDS' etc.)
