 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
