Individual autoconf function broken out of acincludes.m4. This change per the recommended style guide for autoconf and so that individual autoconf functions can more easily be shared across projects. llvm-svn: 16223 2004-09-07 06:56:14 +00:00			`#`

This macro cannot assume that the location of install-sh and mkinstalldirs is in ${srcdir}/autoconf because that is only true if the project is LLVM. For other projects (e.g. sample), we don't want to have to distribute the mkinstalldirs or install-sh programs because it opens a window of breakage for projects. So, this change requires that the llvm_src variable be set up via another AC_CONFIG_COMMANDS call. For LLVM this is done in the configure.ac. For projects its done in the LLVM_CONFIG_PROJECT macro. llvm-svn: 20304 2005-02-24 18:28:20 +00:00			`[AC_CONFIG_COMMANDS($1,`

install-sh chmods to 0755 by default, and this causes 'git diff' to show that all the Makefiles changed mode. Fix this by tellint install-sh to chmod only to 0644, these are not executable files after all! llvm-svn: 80371 2009-08-28 16:12:48 +00:00			`${SHELL} ${llvm_src}/autoconf/install-sh -m 0644 -c ${srcdir}/$1 $1])`
