Configure itself normally tests to find the best shell, which usually 
ends up being 'bash'.  Since /bin/ksh should support this newfangled 
syntax, it seems that it would be wrong for /bin/sh to be selected 
rather than /bin/ksh.  However, it also seems wrong for libtool to be 
relying on ksh features.

Does your Solaris 10 system not have /bin/ksh and /bin/bash?
