When using gcc you don't need another tool :-)
Just use the '-H' option ...

BTW, if you are also interested in predefined cpp macros, try this:
	echo "int main() { return 0; }" >macrotst.C
	g++ -E -dM macrotst.C

And if the C++ specific macros doesn't matter, this is sufficient:
	echo | g++ -E -dM -

Also consider using the verbose flag (-v).
