Okay to apply?

I ask because, even though it fixes an obvious bug, it breaks
binary compatibility with libtool-1.5.x libltdl.  I think the
change only breaks loaders compatibility, and I believe there
are not yet any 3rd party loader.

Does anything outside of libltdl ever copy or take sizeof() lt_dlinfo? If not, then the change does not seem significant and it should be safe to commit.

If actual binary compatability is impacted (i.e. compiled applications stop working), then it can be tricky to get the library versioning correct so that both the head version and the release branch can safely coexist on a system. Blindly following libtool's library revisioning rules for head and release branch can get you into trouble.
