Is there a way to let Android NDK-build use a newer version of gcc?

I installed Android NDK r5b Windows version, and I use cygwin to compile the C code.

I see the NDK-build is actually calling C:\android-ndk-r5b\toolchains\arm-linux-androideabi-4.4.3\prebuilt\windows\bin\arm-linux-androideabi-gcc-4.4.3 to compile. I wonder if there is a way to let NDK-build use a newer version of gcc?

The reason I want to do this is:

Gcc4.4.3 has known bug on generating not optimal assembly code for certain NEON intrinsics
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43118

The newly released GCC 4.6 claims that it has some improvements for ARM and intrinsics. So I want try to have NDK-build use GCC4.6.
