Oh, I see: you posit that the user fixed the shlib configuration problem
after discovering the backend wouldn't run, but did not then go back and
re-run configure. Yes, that makes sense. Justin, are the INT64 flags
in your config.h wrong?

The tests that we have to see whether 64-bit arithmetic actually works
are probably just unnecessary paranoia. However, the tests to see
whether snprintf does the right thing, and with what format flags,
still seem necessary; and I see no way to handle those without a runtime
check.
Maybe the AC_TRY_RUN tests could be moved up to before we start probing
for libraries?
