Ok, given the profound lack of enthusiasm for this patch, I've reworked it a bit. I installed autoconf-2.63 and automake-1.11, so that I'm using the same versions that Jeff did last November. However, with the December update of the top-level libtool files, I still find that I need a few changes. However, these are limited to the configure.in files, and I avoid any modifications to acinclude.m4 or config.hin. Also, given some rumblings on the gcc list about fixing the "config.cache" problem at the toplevel src/ directory, I've removed any changes related to that issue. I still SEE the problem, but it's nothing a complete rm -rf ${builddir} and reconfigure / rebuild cycle can't fix. Sigh. Anyway, if the upcoming top-level src/ changes don't "fix" the problem, I'll repost the omitted bits separately.

The autogenerated changes were created by autoconf-2.63 and automake-1.11. I still think newlib should update to the gcc versions, but I don't want to make that optional element be a blocker for this necessary patch. -- Chuck 2010-02-18 Charles Wilson <...> Work around issues with new libtool files in .. * configure.in: Unconditionally call _LT_PROG_ECHO_BACKSLASH. * iconvdata/configure.in: Ditto. * libc/configure.in: Ditto. * libc/machine/configure.in: Ditto. * libc/machine/i386/configure.in: Ditto. * libc/sys/configure.in: Ditto. * libc/sys/linux/configure.in: Ditto. * libc/sys/linux/linuxthreads/configure.in: Ditto. * libc/sys/linux/linuxthreads/machine/configure.in: Ditto. * libc/sys/linux/linuxthreads/machine/i386/configure.in: Ditto. * libc/sys/linux/machine/configure.in: Ditto. * libc/sys/linux/machine/i386/configure.in: Ditto. * libm/configure.in: Ditto. * libm/machine/configure.in: Ditto. * libm/machine/i386/configure.in: Ditto. * libc/machine/sh/configure.in: Ditto.
