Yes!  This actually does work with the GNU linker if the flag is 
passed early enough on the link line.  There's a slight problem with 
libtool though since it shuffles the flags to put the -Wl,--as-needed 
near the end of the link line.  Even if libtool could be coerced to 
not put the --as-needed near the end of the link line, I'm a little 
wary of using it for cairo since I came across these warnings on the 
internet on Gentoo's page about --as-needed:

"Note: There are known issues with ld shipped with binutils series 
2.16, and early 2.17 prereleases. If you feel like trying this flag, 
you have to use at least version 2.17, that has all the fixes needed 
to have --as-needed behave correctly. Please note that 2.17.50.0.2 
version is not working as one might expect and is, in regard to 
--as-needed, older than 2.17, as it misses a few important fixes."

"Warning: At the time of writing, there are many packages failing in 
funny ways because of --as-needed as they weren't designed to be used 
with it. While there shouldn't be (note the conditional) problems such 
as crashes, this flag is not considered safe for production use"

The other thing is that it doesn't solve the problem for non-GNU based 
systems or tool chains.

Other than that, it does work. :-}
