Subject: Propagate configure flags to sub-configures.
X-Git-Tag: emacs-pretest-24.0.93~232^2~18
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=6c269a38ccd8277a1ecc727db013da020d5dec8a;p=emacs.git

Propagate configure flags to sub-configures.

* Makefile.in (cache_file, ENABLE_MAINTAINER_MODE, CONFIGUREFLAGS):
New macros.
(config.status, bootstrap): Use them to propagate configure flags
to sub-configures.
* configure.in (cache_file): AC_SUBST this, for Makefile.in.
