[gentoo-embedded] Problem cross-compiling gcc-4.3.3 for arm-softfloat-linux-gnueabi

Hiya guys,

I recently got an N810, and decided I should try and setup a Gentoo
build environment for it.  I found some useful pointers at
http://slonopotamus.org/gentoo-on-n8x0 although I didn't follow it to
the letter.  Notably, I tried out ~arm to see how things worked out and
stayed with -Os.  I appeared to run into far fewer bugs than the
original author, and they were mostly configure failing to run a test
because of cross-compilation.

One problem I haven't been able to get around, however, is compiling
gcc-4.3.3.  The error message is below:

Googling for the __NO_INLINE__ message seems to suggest that it's fine
and not a problem, and googling for the fenv_t message turns up about 3
results, none of which seem directly related (I've tried with both Os
and O2 optimization flags and neither's worked).  I've been using the
following autoconf overrides (the commented ones I used only for
compiling the packages mentioned):


ac_cv_func_calloc_0_nonnull=yes
ac_cv_func_malloc_0_nonnull=yes
gl_cv_func_malloc_0_nonnull=yes
ac_cv_func_realloc_0_nonnull=yes
ac_cv_func_memcmp_working=yes
ac_cv_func_strnlen_working=yes

#fixes http://bugs.gentoo.org/224685
gl_cv_func_wcwidth_works=yes

#fixes coreutils-7.1
fu_cv_sys_stat_statfs2_bsize=yes

#fixes popt-1.13
#ac_cv_va_copy=C99
#
#fixes kbd
#ac_cv_func_setpgrp_void=yes


Does anyone have any ideas?  I've tried gcc-4.1.2, but since my host
machine has gcc-4.3.3 I figured it was unlikely to work (and indeed, I
got "must have static linkage" errors quite early on).  I've included my
"emerge-arm-softfloat-linux-gnueabi --info" output further down and I'm
happy to provide any further information or run tests that might help me
sort this problem out.  Any help would be greatly appreciated,

Thanks,

Mike  5:)
