This is a dup of bug 35619.
Workaround: don't build in the source directory.

Moral of the story, follow recommended instructions of building.

*** This bug has been marked as a duplicate of 35619 ***

Build in objdir fails similarly when building libiberty.a  Still has the same multiple definitions.

Can you make sure that your source tree is clean before building in the object directory?

I reinstalled gcc-4.3.0 from the tar.gz file, and extracted it in /usr/local/gcc-4.3.0.  Then I made a completely separate object directory /usr/local/gcc-4.3.0-objdir.  From within that directory I executed ../gcc-4.3.0/configure, then typed make.  The result was the same as in the last comment, multiple defines when building libiberty.a

What version of gcc do you have?
Can you do "gcc -v"?  This has to be a bug with glibc.

Using built-in specs.
Target: x86_64-unknown-linux-gnu
Configured with: ../gcc-4.2.1/configure --enable-languages=c,c++ 
--prefix=/usr/local/share/gcc-4.2.1
Thread model: posix
gcc version 4.2.1

I don't know what changed, but on the same machine with the same circumstances the build completes successfully now.  I can only think that something in the environment changed as a result of updates on the machine, although the version of gcc that builds it now is the same as the one that didn't build it before?:(
