It's probably a result of the various low-level math routines that exist
in libgcc on the PA under hpux.  Under hppa-linux, I don't see any dependence
on libgcc_s.so.1.  However, as expected, libstdc++.so is dependent on
libgcc_s.so.1.

I just checked and libstdc++.sl.4.0 is also linked against libgcc in the
build directory under hpux.  Partly, this problem appears since the
dependencies are encoded as absolute paths under hpux whereas under linux
the dependency for libgcc_s.so.1 is not absolute.

dave@gsyprf11:~/opt/gnu/lib$ ldd libstdc++.so.4.0.0
        libm.so.6 => /home/dave/opt/gnu/lib/libm.so.6 (0x400e7000)
	libgcc_s.so.1 => /home/dave/opt/gnu/lib/libgcc_s.so.1 (0x40176000)
	libc.so.6 => /home/dave/opt/gnu/lib/libc.so.6 (0x40193000)
	/home/dave/opt/gnu/lib/ld.so.1 => /home/dave/opt/gnu/lib/ld.so.1 (0x41000000)

Because of the hard encoding of dependent libraries, libtool normally
relinks applications and shared libraries when they are installed under
hpux.  I suspect that the install process may be using gcc in the build
directory to do this relink.
