gcc-3.3.2 build problems found when building (cross compiler form68k-elf target

A few days ago I started trying to build a Solaris-based cross compiler for an m68k-elf target.
The cross compile FAQ directions that I am following are from
http://www.rtems.com/onlinedocs/releases/rtemsdocs-4.6.0pre5/share/rtems/pdf/started.pdf.
This document describes how to use gcc-3.2.3 to build a cross compiler.
Since I am having problems with 3.3.2, I thought I should report the error I have found thus far.

I started off building and installing binutils-2.14 for a m68k-elf target. No problems.
I installed a copy of the 'newlib' sourcetree from ftp://sources.redhat.com/pub/newlib/newlib-1.11.0.tar.gz
and created a symlink in my gcc build subdir as instructed.

I then setup a build subdir and ran configure as follows:

${SHELL} ../configure \
--prefix=$LOCAL \
--target=m68k-elf \
--program-prefix=m68k-elf- \
--with-newlib \
--enable-threads \
--enable-languages="c,c++" \
--verbose \
# 

Note that the gcc configure apparently supports 'newlib'.
Configure ran fine.
I then ran make and found the 1st error.  Here's an extract from the log.

2496 make: *** [configure-target-libiberty] Error 1

A detailed inspection found that the m68k-elf/libiberty configure tries to run the new cross-compiler (xgcc) to compile & link a small simple
program but the compiler fails because there is no libc.a available to the cross compiler yet.

I made a change to my gcc-3.3.2/libiberty/configure file as follows to fix this error:
2397 ac_link='${CC-cc} -o conftest${ac_exeext} $CFLAGS $CPPFLAGS $LDFLAGS conftest.$ac_ext $LIBS 1>&5'
2398 ac_link='${CC-cc} -o conftest${ac_exeext} $CFLAGS $CPPFLAGS -nostdlib $LDFLAGS conftest.$ac_ext $LIBS 1>&5' #PSC
Note that I have added line 2398 after 2397 to fix the error.
Since the test in question was just a simple test-link, adding the '-nostdlib' seemed sufficient to correct this error.

Now on to the next error encountered.

Note above that I took the 'liberty' of reformatting the xgcc command line to better show what is going on.
The error here seems due to the fact that the cross compiler does not have access to the <sys/types.h> and <string.h>
include files yet. These files exist in the 'newlib' source tree, however they are not being referenced. I should point
out that the directory "/tools/local.m68k-elf/m68k-elf/include" is the correct final location for my cross-compiler however
it has yet to be created. I am still looking into this problem further, but I wanted to report the problems found to date.


Any suggestions would be appreciated.
Thanks.
