Made fixincludes a toplevel build module.
toplevel: 2004-08-31 Paolo Bonzini <bonzini@gnu.org> * Makefile.def (build_modules): Add fixincludes. (dependencies): Make gcc depend on fixincludes. * configure.in (build_tools): Add fixincludes. (build_configdirs): Always include build_libs. * Makefile.in: Regenerate. * configure: Regenerate. contrib: 2004-08-04 Paolo Bonzini <bonzini@gnu.org> * gcc_update: Add fixincludes. fixincludes: 2004-08-31 Paolo Bonzini <bonzini@gnu.org> * .cvsignore: New. * Makefile.in: From gcc/fixinc/Makefile.in, making it fully autoconfiscated. * configure.ac: New. * config.h.in: Generate. * configure: Generate. * aclocal.m4: New. * fixlib.h: Remove inclusions of gcc files. * system.h: New. Other files copied from gcc/fixinc. gcc: 2004-08-31 Paolo Bonzini <bonzini@gnu.org> * Makefile.in (build_subdir): New substitution. (fixinc.sh): Simplify heavily since fixincludes is already built. (stmp-fixinc): Depend on specs.ready. (install-mkheaders): Use new location of fixincludes. (clean): Do not descend into fixinc. (FORBUILD): Replace with ../$(build_subdir). * configure.ac (build_subdir): Substitute. (FORBUILD): Do not set. (all_outputs): Remove fixinc/Makefile. (default commands): Do not create links in fixinc. * mkfixinc.sh: New, from fixinc/mkfixinc.sh without the fixincludes configuration steps and substituting @FIXINCL@ in fixinc.in. * fixinc.in: New, from fixinc/fixincl.sh. * fixinc/*: Removed. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@86824 138bc75d-0d04-0410-961f-82ee72b054a4
