tinyos-help，您好！

	My system: x86_64 processor, gentoo-linux with gcc 4.1.1, TinyOS 2.0 installed from sourceforge

	When I tested my installation by "make micaz sim" in directory $TOSROOT/apps/Null, got error below:

	mkdir -p build/micaz

/home/tos2/tinyos-2.x/tos/lib/tossim/hashtable.c:180: error: cast from 'void*' to 'int' loses precision
make: *** [sim-exe] Error 1

So, I fixed the corresponding error by changing  "if (int(e->v) == 0x477fed00) {" to " if (int64_t(e->v) == 0x477fed00) {". However, another error occurs:

Any suggestion? Is a compatibility problem with gcc 4.1.1?
Thanks in advance.
