[boost] __COUNTER__ vs __LINE__

Hello all, Many of Boost macro APIs PP_CAT symbols with either __LINE__ or __COUNTER__ to make them unique (MPL_STATIC_ASSERT, SCOPE_EXIT, etc). AFAIK, __LINE__ is C++03 standard while __COUNTER__ is only a MSVC extension. I think using __COUNTER__ instead of __LINE__ might allow to expand a macro multiple times on the same line... but a part from that: What's the reason for using __COUNTER__ on MSVC instead of just using __LINE__ for all compilers? Thanks a lot. --Lorenzo -- View this message in context: http://boost.2283326.n4.nabble.com/boost-COUNTER-vs-LINE-tp4286398p4286398.h... Sent from the Boost - Dev mailing list archive at Nabble.com.
