Problem trying to build eglibc for m68k Coldfire MCF54418

[Gilles DOFFE <gdoffe+linux at gmail dot com>]

Hello,

I'm trying to build eglibc 2.19-svnr25243 for a Coldfire MCF54418 (has
no fpu and but has a MMU) with buildroot.

The configuration is this one : (extract from config.log) :
=================
/home/user/buildroot/output/build/glibc-2.19-svnr25243/libc/configure
ac_cv_path_BASH_SHELL=/bin/bash libc_cv_forced_unwind=yes
--target=m68k-buildroot-linux-gnu --host=m68k-buildroot-linux-gnu
--build=x86_64-unknown-linux-gnu --prefix=/usr --enable-shared
--without-fp --with-pkgversion=Buildroot --without-cvs
--disable-profile --without-gd --enable-obsolete-rpc
--with-headers=/home/user/buildroot/output/host/usr/m68k-buildroot-linux-gnu/sysroot/usr/include
=================

But I always get this kind of errors :
=================
In file included from ../sysdeps/ieee754/flt-32/math_private.h:3:0,
                 from ../sysdeps/ieee754/dbl-64/e_exp.c:40:

'SET_RESTORE_ROUND'
   SET_RESTORE_ROUND (FE_TONEAREST);
=================

I always get this errors even if I use -msoft-float in CFLAGS and CXXFLAGS.
Did I miss an option somewhere ?

Since I specified --without-fp in my configure options, should FE_*
macros not be disabled with some #ifdef ?

Thanks in advance for your help,
Gilles
