Correction:  GNU gcc-ld doesn't use dynamic linking.  

GNU gcc is perfectly happy with dynamic linking, *IF* you *DON'T* use
gcc-ld with it.  You should have it use the Sun ld.  The gcc-ld appeared on
my network when GNU g++ was compiled, at which point I noticed all my
gcc-compiled executables had become huge.  I edited the source to g++
to arrange for it to look for "gcc-ld++" instead of "gcc-ld", moved
gcc-ld to gcc-ld++, reinstalled g++, and LO:  no more problem.

This happened on both the Sun 3 and 4's here.

Example dynamic from the binaries used on our Sun 4/390, SunOS 4.1, X11R4:

}-0.134-> file Xsun
Xsun:           sparc demand paged dynamically linked executable not stripped
}-0.135-> nm Xsun | grep gcc
00002f50 t gcc_compiled.
0009da60 t gcc_compiled.
00097458 t gcc_compiled.
0009af48 t gcc_compiled.
00099170 t gcc_compiled.
}-0.136-> ldd Xsun
        -lsunwindow.0 => /usr/lib/libsunwindow.so.0.40
        -lpixrect.2 => /usr/lib/libpixrect.so.2.4
        -lc.1 => /usr/lib/libc.so.1.3
}-0.137-> ls -Flasg Xsun
 808 -rwxr-xr-x  1 harp     netadm     819200 Jun 25  1990 Xsun*

(I do seem to remember difficulty in compiling the server, unrelated to
 the dynamic-linking wierdness noted above.  Also, I have not replaced
 *all* of the sparc binaries which were accidentally statically linked.
 Be warned.)
