Right.  I suspect many gcj users avoid static libs for this reason.

Well... you don't need admin privs to install/use a DSO in a user
directory.  Perhaps a tarball of executable + DSOs doesn't meet your
standalone requirement though.

If you require no dependencies on libgcj.so or libgcc_s.so, it'll be far
simpler to configure/build gcj/libgcj with --disable-shared than
dealing with -nostdlib and all the required libraries (IMO, having done it
both ways myself) especially if you need a portable makefile.

I did just that with an uberbaum tree on RH 7.3, to create an executable
that runs on any Red Hat release >= 7.3.  (If you don't use an uberbaum or
otherwise unified GCC tree, make sure you get up-to-date binutils from
somewhere.  The gas distributed with RH 7.3 is no longer sufficient to
build the 3.4 branch, for instance.)

Good luck,

Jeff
