[Buildroot] Need some help with uClibc build

Can somebody, please, help me.
I seem to be missing something trivial like the fact that
gcc-4.3.1+ would not work with uClibc-0.9.29, or something like this.
I'm trying to build buildroot with
binutils-2.19
uClibc-0.9.29
gcc-4.3.1
I managed to configure and build everything including the compiler.
But then, uClibc build did not go through :
CC libc/sysdeps/linux/common/chdir.os
In file included from ./include/sys/param.h:22,
from libc/sysdeps/linux/common/chdir.c:13:
./include/limits.h:124:26: error: limits.h: No such file or directory
make[2]: *** [libc/sysdeps/linux/common/chdir.os] Error 1
make[1]: *** [lib/libc.so.0] Error 2
I figured that using extra GCC flag "-D_GCC_LIMITS_H_" would help.
It did. But then, another problem raised up :
CC libc/sysdeps/linux/common/nice.os
libc/sysdeps/linux/common/nice.c: In function 'int_add_no_wrap':
libc/sysdeps/linux/common/nice.c:33: error: 'INT_MIN' undeclared (first
use in this function)
libc/sysdeps/linux/common/nice.c:33: error: (Each undeclared identifier
is reported only once
libc/sysdeps/linux/common/nice.c:33: error: for each function it appears
in.)
libc/sysdeps/linux/common/nice.c:35: error: 'INT_MAX' undeclared (first
use in this function)
make[2]: *** [libc/sysdeps/linux/common/nice.os] Error 1
I guess I might be missing some trivial knowledge about how things work
with each other.
If you can share with me this knowledge I would really appreciate it.
Thanks in advance for any of your help,

P.S. Some background on my project. Xtensa GNU/Linux is successfully
building with
binutils-2.18
uClibc-0.9.29
gcc-4.2.1
with relatively recent buildroot update.
I'm trying to upgrade the compiler, which is important for our projects.
