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.
