Entirely my fault -- I had been resetting CFLAGS and friends in debian/rules,
which lead to the all-important  -std=gnu99   being dropped from the compiler
flags.  And gcc up to version 3.4.* seems to forgive this, whereas 4.*
versions want it.  

Thanks, Dirk

Hell, there are no rules here - we're trying to accomplish something.
