GCC 4.3.4/290-index_macro.patch also needed for 4.4.x in crosstool-NG

[Joachim Nilsson]

Hi Yann!

It seems I need to add the 4.3.4/290-index_macro.patch to the GCC 4.4.x 
series as well.  I immediately trigger the following libstdc++ bug for 
4.4.2 with a uClibc .config which has UCLIBC_SUSV3_LEGACY_MACROS set[1].

     http://lists.busybox.net/pipermail/uclibc/2006-April/035991.html

The linked post has UCLIBC_SUSV3_LEGACY=y but the patch seems to apply 
well to both cases.

Btw. the armeb-unknown-linux-uclibc* samples have CONFIG_ARM_OABI=y and 
CONFIG_ARM_EABI is not set in their uClibc-0.9.30.1.config. I don't know 
if it matters, but I found it a bit peculiar.

Regards
  /Joachim

[1] - index()/rindex() etc.

OK, will do. Thanks.
Do you mean that you managed to overcome the previous issues as well?

It should not matter, as the uClibc build script in crosstool-NG mangles
the .config file with appropriate values depending on the configuration,
and EABI/OABI is such a config knob that gets mangled, look at:
  scripts/build/libc/uClibc.sh@200

BTW, this code is plain wrong when ARCH != arm. Will fix.

Nope, I started focusing on other things meanwhile, like adapting the 
uClibc .config to suit my needs better, as well as look into strace and 
ltrace.

At least the toolchain builds on 64-bit for me now.  Will look into the 
gcc build on 32-bit again later, unless you beat me to it.

Aha, cool! :)
