Problem easily solved. In boost test builds using gcc use -Wsystem-headers to turn the warnings back on. That's too broad in effect. It would enable warnings in headers

Yep, it would.
The best approach likely is a library specific mechanism that, by default, honors a Boost-wide config to disable warnings using #pragma GCC system_header.
I think that any such mechanism would need to be wrapped with a BOOST_TESTED_AT(...) to make sure that real warnings highlighted by new versions of the compiler didn't sneak through. It isn't reasonable to assume that the library author will immediately test all new GCC releases with the pragma disabled. Phil -- Phil Richards, <news@derived-software.ltd.uk>
