1752*** Warning: Releases of GCC earlier than version 3.0 cannot reliably
1753*** create self contained shared libraries on Solaris systems, without
1754*** introducing a dependency on libgcc.a.  Therefore, libtool is disabling
1755*** -no-undefined support, which will at least allow you to build shared
1756*** libraries.  However, you may find that when you link such libraries
1757*** into an application without using GCC, you have to manually add
1758*** \`gcc --print-libgcc-file-name\` to the link command.  We urge you to
1759*** upgrade to a newer version of GCC.  Another option is to rebuild your
1760*** current GCC to use the GNU linker from GNU binutils 2.9.1 or newer.
