What version are you using? When SPL is too large a build-time failure
is expected.

My issue is that code that is compiled but eliminated because it's not called leaves behind all of its anonymous strings ("like this"). In my latest build I have the following sections that are all anonymous strings:
This is http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54303 which seems to
have gotten little attention after initial triage. I guess I need to
find a little time to show it's still there.

One option would be to add a "disable all output" option to SPL that
would get all of the strings dropped. I'm not sure how cleanly this can
be done, but I know it has been done.
Another option would be to do some careful splitting and #ifdef'ery of
files so that we can just never link in the stuff with strings we don't
need.
