From eea5e1ee1429ceb1a725f598ba1bf61961480fef Mon Sep 17 00:00:00 2001 From: jsm28 Date: Sun, 18 Nov 2001 19:46:58 +0000 Subject: * doc/install-old.texi: Move some sections out to ... * doc/collect2.texi, doc/configfiles.texi, doc/headerdirs.texi: ... here. New files. Make into chapters rather than sections. * doc/gcc.texi: Include the new files and add menu entries for them. * Makefile.in ($(docdir)/gcc.info, gcc.dvi): Update dependencies. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@47150 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/doc/headerdirs.texi | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 gcc/doc/headerdirs.texi (limited to 'gcc/doc/headerdirs.texi') diff --git a/gcc/doc/headerdirs.texi b/gcc/doc/headerdirs.texi new file mode 100644 index 00000000000..17db57f0560 --- /dev/null +++ b/gcc/doc/headerdirs.texi @@ -0,0 +1,33 @@ +@c Copyright (C) 1988, 1989, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001 Free Software Foundation, Inc. +@c This is part of the GCC manual. +@c For copying conditions, see the file gcc.texi. + +@node Header Dirs +@chapter Standard Header File Directories + +@code{GCC_INCLUDE_DIR} means the same thing for native and cross.
