Add autoconf as a host tool, not built by default. 2001-11-14 23:05:23 +03:00			`# $NetBSD: Makefile.gnuwrap,v 1.7 2001/11/14 20:05:23 tv Exp $`
Major overhaul of src/tools and host toolchain. Summary of changes: * Rewrite src/tools Make logic to work like the rest of the tree wrt "dependall" and "install". The old "make build" hack is gone. * Remove the MKTOOLS logic. This was linked to the "make build" hack, and was only needed because TOOLDIR originally had no writable default. * Redo the GNU configure/make logic to make it fit reasonably in a BSD make wrapper. Use new ${.ALLTARGETS} variable to scan for targets in $(srcdir), and mark them with .MADE: to prevent rebuilding. * Only build cross tools in src/tools; remove some messy logic in src/usr.* and src/gnu/usr.* that would do target filename rewriting (improves consistency and readability). * Add the ability to build cross gdb at tool build time by setting MKCROSSGDB (default no) to "yes" in mk.conf. * Add src/tools/groff and set up paths to work with this cross groff. 2001-11-13 02:16:17 +03:00			`#`
			`# Wrapper for GNU Makefiles.`

Don't put commands in the suffix rule override (avoids target graph cycles). Protect from multiple inclusion. 2001-11-13 09:03:41 +03:00			`.ifndef _WRAPPER_INCLUDED`

Make the wrapper work correctly for groff too, which uses a rather freaky Makefile layout. 2001-11-13 07:28:27 +03:00			`.ifndef _NOWRAPPER`
