[SVN r68640]
Refs #4987 . Added forward declaration of namespace-scope swap for boost::optional, this should fix GCC compilation errors. Also swap implementation now uses Boost.Utility.Swap to make use of the workarounds for some broken compilers. If it breaks for your compiler, let me know in the mentioned ticket.

Andrey Semashev	e9989b260e	Refs #4987 . Added forward declaration of namespace-scope swap for boost::optional, this should fix GCC compilation errors. Also swap implementation now uses Boost.Utility.Swap to make use of the workarounds for some broken compilers. If it breaks for your compiler, let me know in the mentioned ticket. [SVN r67288]	2010-12-17 21:12:56 +00:00
Andrey Semashev	646488e0e2	operator>> behavior changed slightly so that the stream is not accessed when unrecognized character sequence is detected. [SVN r67184]	2010-12-12 11:35:19 +00:00
Andrey Semashev	64d8062621	The may_alias workaround is also disabled for GCC prior to 3.2. Also added description for this workaround. [SVN r67112]	2010-12-08 18:32:36 +00:00

Daniel James	57c07c7a57	Fix doc build for 2 libraries which use own css. I changed the default to use doc/src/boostbook.css. So add an explicit location to libraries which use their own stylesheet. [SVN r64170]	2010-07-19 20:17:58 +00:00
Daniel James	97e314f03a	Fix some header links. [SVN r64006]	2010-07-14 08:15:33 +00:00
Daniel James	bccd75c72f	Update various libraries' documentation build. Mostly to use the images and css files under doc/src instead of doc/html, usually be deleting the settings in order to use the defaults. Also add 'boost.root' to some builds in order to fix links which rely on it. [SVN r63146]	2010-06-20 18:00:48 +00:00
Douglas Gregor	16f0a0aaaf	Expose the "types" typedef of boost::optional_detail::operator_base as public, rather than protected, since Spirit pokes at this typedef. [SVN r61832]	2010-05-06 21:44:18 +00:00
