[any][quickbook] Recent compile failure gcc vs. clang..

The same error is seen with '--std=c++-98': http://www.boost.org/development/tests/trunk/developer/output/DebSidC++-boos... But regardless, I'm not sure how well gcc 4.2 will be supported in the future. It's a pretty old compiler.

Committed fix in r84236 to trunk. Can you reproduce the error now? -- Best regards, Antony Polukhin

IIRC.. Isn't it still one of the compilers we consider as a release requirement?

Seems to be fixed now.. Thanks for the quick work! -- -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com -- 102708583/icq - grafikrobot/aim - grafikrobot/yahoo

Sorry, I meant specifically supported by quickbook, which isn't held to the same requirements as libraries. It doesn't have any official requirements, but practically, it needs to be possible to build it on all current development platforms. Clang support should be enough for OS X. The documentation build is actually done on a broken macbook (I can still ssh in), which is stuck on Leopard, but I build using macports gcc. But regardless, there's no specific version of any compiler which is a release requirement. Libraries are required to be portable to at least two popular operating systems (effectively windows and things that resemble unix). GCC 4.2 used to be required for OS X, but clang support is probably enough nowadays. Although, a library such as Boost.Any effectively has stricter requirements since other libraries rely on it. And in this case, there was also a problem with later compilers in C++98 mode.

Regardless of whether GCC 4.2 should be supported or not, in C++03 T& is invalid if T is already a reference. It's a good thing that GCC 4.2 could catch this issue.

Nobody was suggesting it was an incorrect error. And I've already pointed out, I was referring to quickbook.
