"info ld" says that -dy and -Bdynamic, and -dn and -Bstatic are aliases.
Your versions work though - thanks! (I think it was the "-Wl," that made
the difference).

It wasn't fltk causing the problem after all (btw, my gcj == 3.0.2).
I was doing a Class.forName, which as you pointed out would cause problems
when libgcj was linked statically.  I now have all libraries apart from
libgcj linked statically and it works great.
Thanks again for your help.
