I believe the reason we do that is that we want to find flags that will
not result in the compiler generating a warning during each and every
source compile. Most developers would consider such a behavior broken,
and not without good reason.

[ shrug... ] Given the lack of previous complaints, it works 99.999%
of the time, which is about as much reliability as can be hoped for in
most autoconf tests :-(. I'm afraid we can't help you without breaking
it worse for a larger number of other people.
