 When I tried to build the boost libraries under gcc 3.4 unix Solaris, I
 repeatedly got an error message that looked like


 {{{
 /var/tmp//ccdt31Ke.s: Assembler messages:
 /var/tmp//ccdt31Ke.s:619: Error: Architecture mismatch on "cas".
 /var/tmp//ccdt31Ke.s:619:  (Requires v9|v9a|v9b; requested architecture is
 v8.)
 }}}


 I traced the problem to the following lines in
 <detail\sp_counted_base.hpp>:

 {{{
 #elif defined(__GNUC__) && ( defined( __sparcv8 ) || defined( __sparcv9 )
 )

 # include <boost/detail/sp_counted_base_gcc_sparc.hpp>
 }}}

 which call the following command:

 {{{
     __asm__ __volatile__( "cas %0, %2, %1"
                         : "+m" (*dest_), "+r" (swap_)
                         : "r" (compare_)
                         : "memory" );
 }}}

 It looks like __sparcv8 is not sufficient to call this command, only
 __sparcv9 is.  Note also the <detail/sp_counted_base_solaris.hpp> is
 apparantly never included.
