gcc 4.9.0 do not build on OSX

["Franzi Edo." <edo dot franzi at ukos dot ch>]

Hi,
I am trying to build a gcc-4.9.0 ARM cross compiler on OSX Mavericks unsuccessfully.
My toolchain works fine with the previous version 4.8.2 but on the 4.9.0 I have this error during the gcc building pass 1.

/opt/uKOS/Packages/gcc-4.9.0/gcc/config/arm/neon.md:3486:10917: fatal error:
     bracket nesting level exceeded maximum of 256
/opt/uKOS/Packages/gcc-4.9.0/gcc/config/arm/neon.md:3486:10917: note: use
     -fbracket-depth=N to increase maximum nesting level
32 warnings and 1 error generated.
make[1]: *** [insn-attrtab.o] Error 1
make: *** [all-gcc] Error 2
Error building gcc pass 1

So, I tried to increase the number of nesting level as indicated (-fbracket-depth=1024) but I get the same error.
I use these packages:

GMP_VER=6.0.0
MPFR_VER=3.1.2
MPC_VER=1.0.2
BIN_VER=2.24
GCC_VER=4.9.0
NLB_VER=2.1.0
GDB_VER=7.7

The configure for the pass 1 is:

export GCC1_CONFIG=" \
	--enable-interwork \
	--enable-languages=c,c++ \
	--with-newlib \
	--with-headers=${PATH_TOOLS_GCC}/Packages/newlib-${NLB_VER}/newlib/libc/include \
	--with-mpfr=${PATH_TOOLS_GCC}/cross/mpfr-${MPFR_VER} \
	--with-gmp=${PATH_TOOLS_GCC}/cross/gmp-${GMP_VER} \
	--with-mpc=${PATH_TOOLS_GCC}/cross/mpc-${MPC_VER}"

Any idea? 
Regards,
 Edo
