Please CC all binutils bug reports to binutils@sourceware.cygnus.com.
If it can be duplicated in my Linux bintuils, also CC to hjl@lucon.org.

I don't think ld should check those DSOes brought in by DT_NEEDED. FYI,
glibc 2.2.3 requires a gcc with the patch
http://gcc.gnu.org/ml/gcc-patches/2001-03/msg01164.html
installed. gcc 2.96-81 in RedHat 7.1 is ok. gcc 2.95.3 is NOT ok. The
gcc in CVS has that patch.
