Should clang support more gcc options?

I wish to test clang by compiling some packages with the following commands:

./configure
make CC=clang CFLAGS=-fsyntax-only

But it turns out that clang does not accept a lot of gcc options, such as -c, -O, etc.
Shall we make clang just accept them as dumb options to make it a drop-in replacement for gcc? This can facilitate the testing of clang a lot.

I sent a bash script that allows this a few days ago: http://lists.cs.uiuc.edu/pipermail/cfe-dev/2007-December/000613.html

The bug I reported in that mail is not yet fixed too.
