Here are the details:

Without OPTION_ANDROID=0:

../../../gcc/gcc/c-family/c-cppbuiltin.c: In function ‘c_cpp_builtins’:
../../../gcc/gcc/c-family/c-cppbuiltin.c:841: error: ‘OPTION_ANDROID’ 
undeclared (first use in this function)
../../../gcc/gcc/c-family/c-cppbuiltin.c:841: error: (Each undeclared 
identifier is reported only once
../../../gcc/gcc/c-family/c-cppbuiltin.c:841: error: for each function 
it appears in.)

Without LIBC_BIONIC=3:

Without LIBC_GLIBC=1:

../../../gcc/gcc/builtins.def:178: error: ‘LIBC_GLIBC’ undeclared (first

Building and testing the moxie-uclinux toolchain with the HEAD of GCC
is very simple:

$ git clone git://github.com/atgreen/moxiedev
$ cd moxiedev/gcc
$ ../scripts/fix-svn.sh
$ ./contrib/gcc_update
$ cd ..
$ PATH=`pwd`/root/usr/bin:$PATH
$ ant build


Thanks,
