svn path=/branches/release/boost/type_traits.hpp; revision=79191
Merged more changes (bug fixes, especially hopefully fixing the VC++ test failure) from trunk

Merged bug fix from trunk

svn path=/branches/release/boost/type_traits.hpp; revision=79393
Merge changes from trunk:

Fix PDF install rule so that it's explicit and automatically invokes a PDF build when specified on the command line.
So "bjam pdfinstall" will now build and install the PDF to the current directory.
This works around some problems that the previous versions had if the user did not have an FO processor installed (basically Daniel James was unable to build the HTML docs for the distribution if the pdfinstall rule was implicit).
