limits.h

Hello.

I'm using gcc-3.2 for arm-elf target.
Configure command line is:

--host=i686-pc-linux-gnu --target=arm-elf --enable-libstdcxx-v3 
--with-target-short-wchar --norecursion --with-headers=/home/... 
--with-headers=/home/...

I'm using gcc with Newlib-1.11.0.

I need to have correct MB_LEN_MAX macro in my programs. This correct 
value is defined in Newlib's limits.h. But gcc masks Newlib's limits.h 
by its own limits.h version witch defines MB_LEN_MAX as 1. GCC's 
limits.h doesn't include Newlib's limits.h recursively.

GCC 3.2.2 on my RH9 Linux host doesn't has such problem - his limits.h 
have a directive '#include_next <limits.h>'.

I need to have such a directive in my gcc-3.2. How can I do this?

It seems that limits.h is generated file - there is no such file in gcc 
sources. Also, as I've found, gcc-3.2 adds such '#include_next' when is 
configured to i386-linux target. Some utility 'fixinc' exists in gcc 
source tree which as I've investigated fixes gcc's includes.

Please, tell me how to fix gcc-3.2. May be I should add some 'configure' 
option... Any helpful links ?

Thanks a lot.

Artem.
