Summary:                    GCC 4.6.2 C++ : dynamic link  issue
Description: 
The minimal program:

int main() {}

compiles, links (g++ -o c c.cc) but doesn't run; the following error
message is reported:

        ld.so.1: c: fatal: libstdc++.so.6: open failed: No such file or
        directory

and ldd reports:
	libstdc++.so.6 =>	 (file not found)
	libm.so.2 =>	 /lib/libm.so.2
	libgcc_s.so.1 =>	 (file not found)
	libc.so.1 =>	 /lib/libc.so.1

$ type g++

---------------------------------------------------------------------- 
a temporary solution to this is:

gcc -dumpspecs > /opt/csw/lib/gcc/i386-pc-solaris2.10/4.6.2/specs

change the directive *link_arch from :

%{m64:%{G:-G}    %{YP,*}    %{R*}  %{compat-bsd:      %{!YP,*:%{p|pg:-Y
P,/opt/csw/lib:/usr/ucblib/64:/usr/lib/libp/64:/lib/64:/usr/lib/64}        
     %{!p:%{!pg:-Y P,/usr/ucblib/64:/lib:/usr/lib/64}}}              -R
/usr/ucblib/64}    %{!compat-bsd:      %{!YP,*:%{p|pg:-Y
P,/usr/lib/libp/64:/lib/64:/usr/lib/64}              %{!p:%{!pg:-Y
P,/lib/64:/usr/lib/64}}}}}%{!m64:%{G:-G}    %{YP,*}    %{R*}   
%{compat-bsd:      %{!YP,*:%{p|pg:-Y

             %{!p:%{!pg:-Y P,%R/usr/ucblib:%R/usr/ccs/lib:%R/usr/lib}}}    
         -R %R/usr/ucblib}    %{!compat-bsd:      %{!YP,*:%{p|pg:-Y
P,%R/usr/ccs/lib/libp:%R/usr/lib/libp:%R/usr/ccs/lib:%R/usr/lib}           
  %{!p:%{!pg:-Y P,%R/usr/ccs/lib:%R/usr/lib}}}}}

to :

%{m64:%{G:-G}    %{YP,*}    %{R*} -R /opt/csw/lib   %{compat-bsd:     
%{!YP,*:%{p|pg:-Y
P,/opt/csw/lib:/usr/ucblib/64:/usr/lib/libp/64:/lib/64:/usr/lib/64}        
     %{!p:%{!pg:-Y P,/usr/ucblib/64:/lib:/usr/lib/64}}}              -R
/usr/ucblib/64}    %{!compat-bsd:      %{!YP,*:%{p|pg:-Y
P,/usr/lib/libp/64:/lib/64:/usr/lib/64}              %{!p:%{!pg:-Y
P,/lib/64:/usr/lib/64}}}}}%{!m64:%{G:-G}    %{YP,*}    %{R*}   
%{compat-bsd:      %{!YP,*:%{p|pg:-Y
P,%R/usr/ucblib:%R/usr/ccs/lib/libp:%R/usr/lib/libp:%R/usr/ccs/lib:%R/usr/lib}
             %{!p:%{!pg:-Y P,%R/usr/ucblib:%R/usr/ccs/lib:%R/usr/lib}}}    
         -R %R/usr/ucblib}    %{!compat-bsd:      %{!YP,*:%{p|pg:-Y
P,%R/usr/ccs/lib/libp:%R/usr/lib/libp:%R/usr/ccs/lib:%R/usr/lib}           
  %{!p:%{!pg:-Y P,%R/usr/ccs/lib:%R/usr/lib}}}}}

Note that this is not complete and specific to the Intel architecture.

To complete, you must manage 32 and 64 bit, profiling and debugging.

For the SPARC architecture the file's path is slightly different.
