Hi,

Our Boost build is a subset of all the modules. After upgrading to Boost
1.68.0, our build is now failing on the program_options target. It does
appear to produce the program_option dll's, but not the export libs.

To be honest, I don't even know what target is including program_options,
because we don't explicitly include program_options in the bcpCopy command.
I'm assuming filesystem by the looks of the following output.

Here is the output from the debug build (the same is seen in release):

To describe the build more completely, we do the following:

bootstrap.bat
b2 tools/bcpCopy
dist\bin\bcp --namespace=xxx smart_ptr filesystem array.hpp container move
ptr_container algorithm/string.hpp tokenizer.hpp thread chrono atomic
foreach.hpp uuid integer asio crc config context build predef
E:\our\boost/xxx
(from bcpCopy target dir)
src\b2 --without-test --prefix=E:\our\boost --build-dir=build
link=shared,static threading=multi runtime-link=shared toolset=msvc-14.1
architecture=x86 address-model=64 variant=debug,release stage

This same build process worked fine with Boost 1.59.0 on msvc 14, 12, and
11.

Kevin
