No, there are not. We have tied boost version numbers and boost
library abi to the GCC and libstdc++ ABI.

Please don't. Or if you do, you must use a different abi suffix tag.

Becuase boost1.62 compiled with pre gcc-6 will have different ABI. And
applications compiled against boost1.62-non-gcc6-abi will fail to work
with Debian's boost1.62-with-gcc6-abi in testing.

Same boost compiled with pre-gcc6 and gcc6 have different ABI, and
libraries & applications compiled against different boost ABIs are
incompatible too.

Please don't, as it will cause a dependency hell nightmare on upgrades.
