This reverts commit 4610afc49e9c94bdc084cb13cceeec5912326dc6, reversing
changes made to 6623bde4fe501258a54746273ac337e3d55a6710.
Add hello_filesystem.cpp and related infrastructure so we have a handy starting point for building quick tests.
Initial commit before merge from ts-develop.
git checkout --patch ts-develop doc/tickets.html
Remove use of <boost/test/prg_exec_monitor.hpp>. It has caused trouble for years, and I'm tired of fighting with it. The last straw was adding a Cygwin gcc toolset, only to have <boost/test/prg_exec_monitor.hpp> fail to link. Change to always use <boost/detail/lightweight_main.hpp>, which is trouble-free.
Replace more <boost/test/prg_exec_monitor.hpp> usage with <boost/detail/lightweight_main.hpp>.
Add __OpenBSD__ to the operating systems that "expect their string parameters to be in UTF-8 encoding and nothing else." Fixes #8352
9054 and 10228 are now closed.
Add non-const overloads for the value_type and string_type to avoid calling codecvt(). Fixes ticket #9219.
Add 9219.cpp plus infrastructure and path.cpp logging
Update release history.
Remove comments about mutexes. They are a distraction and less relevant as C++11 support becomes widespread.
