[boost] [lambda][test] _set_se_translator() requires /EHa

I was looking at one of the failures on vc 7.1 and noticed that there was the following warning: ..\boost\test\impl\execution_monitor.ipp(825) : warning C4535: calling _set_se_translator() requires /EHa the command line options /EHc and /GX are insufficient See: http://beta.boost.org/development/tests/release/developer/output/daw-msvc71-... or: http://tinyurl.com/5osfqr Is this a spurious warning, or is really an issue? Thanks, David
