problems building libvorbis-1.2.0 on Solaris 10 (sparc)

Hello,

I'm running into problems while trying to build libvorbis.  My build
platform is Solaris 10 (sparc) (11/06) with GCC 3.4.6.

The build fails with the following error :


Making all in examples

The build works fine under Solaris 9.  Any ideas ?


Thanks for any help one can provide.
