9829	incorrect coding when BOOST_NO_CXX11_RVALUE_REFERENCES is defined	melanie.blower@…	John Maddock	"Hello!
I'm trying to compile hhvm (hip hop vm) with the Intel compiler using gcc 4.8.2 headers, and boost 1.54

This version of boost, configured for the Intel compiler, defines BOOST_NO_CXX11_RVALUE_REFERENCES, and the substitute code which is supplied for this configuration is incorrect. It causes a compilation problem in hhvm. I confirmed that by attempting to compile the file using g++ and -DDBOOST_NO_CXX11_RVALUE_REFERENCES, and g++ reports the same issue.

In a separate ticket I'll file requests to modify the availability of rvalue references based on Intel compiler version (or EDG symbols). The currently available Intel compiler does provide rvalue references

Attaching the preprocessed output from the Intel compiler

Thanks and regards, Melanie
