Can somebody please explain my problem here with building shared libraries
with G++.  This compile works properly when built using Sun C++2.1, and it also
works when built statically using G++.

I'm using G++ 2.3.3 linking with Sun's linker under SunOS 4.1.3.

I get a bunch of unresolved symbols which are all defined in libxs.sa.0.1,
as C [common] type symbols (different from Sun C++2.1 which defines
them as D [data] type symbols).  I tried using the -fno-common flag to G++
which changed the symbol definitions to D, but didn't help at all.

Your help would be appreciated.

Then I used the -v option on GCC to find out the command it was using and I
tried making it use the sun linker:

[mizar:/proj/dv/xs/src] /bin/ld -e start -dc -dp -o xsdemo /lib/crt0.o -L. -L/u
sr/local/lib/gcc-lib/sun4/2.3.3 -L/usr/local/lib xsdemo.o -lxs -lX11 -lg++ -lm
-lgcc -lc -lgcc
<same link errors here too>
