We will need a patch that works for the versions of SunPro providing __typeof__. But shouldn't this be part of Boost.Typeof? Could you provide such a patch?
Yes Boost.Typeof needs patching as well, ...
Boost.Typeof already appears to use __typeof__: #elif defined(__SUNPRO_CC) # if (__SUNPRO_CC < 0x590 ) # ifdef BOOST_TYPEOF_NATIVE # error native typeof is not supported # endif # ifndef BOOST_TYPEOF_EMULATION # define BOOST_TYPEOF_EMULATION # endif # else # ifndef BOOST_TYPEOF_EMULATION # ifndef BOOST_TYPEOF_NATIVE # define BOOST_TYPEOF_NATIVE # endif # define BOOST_TYPEOF_KEYWORD __typeof__ # endif # endif
... but note that since one goal of the rewrite is to reduce the libraries dependencies, Boost.Typeof is used as a last resort in common_type, and typeof is used directly when available.
Do we have to use Typeof in common_type at all? In the cases in which
