In the past, b2 would build libraries named like so: libboost_atomic-gcc48-mt-d-1_60.so (note -gcc48-)

I tried compiling Boost 1.66.0 (from boost-git) with gcc 8.3.0,

library it generates is named:

Possibly, it's related to the change in GCC 5+ versioning. This was accommodated in Boost.Build in October 2018 https://github.com/boostorg/build/pull/349 that is, in Boost 1.69 (boostorg/build should use milestones for issues, IMO)

Excellent, thanks for that reference.

I don't think it's possible for a change in 1.69 to affect how 1.66 is built. Something else must be wrong.

The order events was something like this: original: Boost.Build originally uses gcc48, for example. - gcc -dumpversion only returns the major version. This no longer matches the regex in common.jam, causing the version in the library name to be blank. - Boost.Build is adjusted to use -dumpfullversion instead, restoring the original library naming. - Boost.Build is adjusted to include only the major version in the library name (the change Mateusz mentioned).
