I disagree. We have unit tests. For many packages, math.h related test
failures - and especially 'long double' related test failures - are
acceptable. The person who runs "make check" can surely evaluate the
severity of a test failure.
Having configure die is the worst possible behaviour, because it elevates
the issue to severity 1 / BLOCKER.
