Hi,

during the test of boost-1.63 rc 1 some problems occurred (see Marshall's
and Stephan's postings).

I request to merge my last commits (on branch master) from boost.context
and boost.fiber into boost-1.63 (rc 2?) - as well as commit
13f5d9c88ae5363fe547f04c1d272b2a772a8b4d
from boost.config.

Otherwise the build will fail for gcc-7.1, clang-4.0 and mingw64.

best regards,
Oliver
