Here's another that doesn't like --as-needed (with error). This is being compiled on gcc-3.4.6-r1
www-misc/htdigs-3.2.0_beta6



(cd .libs && rm -f libfuzzy.so && ln -s libfuzzy-3.2.0.so libfuzzy.so)

Here's another one that doesn't like LDFLAGS="-Wl,-O1,--as-needed"
cppunit-1.10.2
(needed for kmymoney2)

orbit-0.5.17-r1 does not compile with LDFLAGS="-Wl,-O1,--as-needed"
(does compile with these LDFLAGS turned off)

This was a real eye-opener for me, I'd like to give it a shot. Using --as-needed won't remove (possible) debugging symbols will it?

(Sorry for posting here, but is the fastest way...)

The mentioned version of binutils in the "--as-needed fixing guide" is wrong. binutils-2.16.91.5 are not available. The latest version in portage is bintils-2.16.91.0.7.
