State-Changed-Why:
    libgcc.a should be installed in $prefix/lib/gcc-lib/$target/$version/.
    If that didn't happen, something's wrong.
    
    That said, note that the shared libgcc default is with the
    "g++" driver program, not the "gcc" driver program.  A point
    of possible confusion that appears to be present in your
    problem description.

>Description:
Info says the effect of -shared-gcclib should be the
default when linking a C++ main program (only the shared
version libgcc_s.so is installed by gmake-install).

Sometimes I find I have to specify -shared-libgcc
explicitly to avoid undefined symbols in libstdc++
at link time

gcc -v indicates that -lgcc is passed to collect2 unless
I specify -shared-libgcc. But no libgcc.a is installed,
only libgcc_s.so.
>How-To-Repeat:
Simple HelloWorld C++ program using cout. Compile with
gcc -v. Note that "-lgcc" is passed to collect2 rather
than "-lgcc_s" unless -shared-ligcc is passed. It results
in undefined symbol errors at link time in some cases.
