Building gcc 3.0.4 on Red Hat with --enable-threads=posix

["JMonk" <jmonk at panix dot com>]

I must be missing something here, but I can't get gcc to build with the
option (--enable-threads=posix) set.

<<Some system details BTW:

	mahler:~/gcc/gcc$ uname -a
	Linux mahler 2.4.2-2 #1 Sun Apr 8 20:41:30 EDT 2001 i686 unknown
	mahler:~/gcc/gcc$ g++.2.96 -v
	Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/2.96/specs
	gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-81)
	mahler:~/gcc/gcc$ rpm -qa | grep glib

I can perform the default install, as follows:

	mahler:~/gcc/gcc$ cat config.status
	#!/bin/sh
	# This file was generated automatically by configure.  Do not
edit.
	# This directory was configured as follows:
	../gcc-3.0.4/configure
--with-gcc-version-trigger=/home/jmonk/gcc/gcc-3.0.4/gcc/version.c
--host=i686-pc-linux-gnu --norecursion 
	#  using "mt-frag"

But when I add " --enable-threads=posix", as follows:

	mahler:~/gcc/gcc$ cat config.status
	#!/bin/sh
	# This file was generated automatically by configure.  Do not
edit.
	# This directory was configured as follows:
	../gcc-3.0.4/configure
--with-gcc-version-trigger=/home/jmonk/gcc/gcc-3.0.4/gcc/version.c
--host=i686-pc-linux-gnu --enable-threads=posix --norecursion 
	#  using "mt-frag"

The install fails, as follows:
